1 Creating HyperLynx DDRx Memry Cntrller Timing Mdel AppNte A P P N T E S SM Creating HyperLynx DDRx Memry Cntrller Timing Mdel By: Min Maung Last Mdified: April 30, ntrductin The DRAM and Cntrller timing mdels are required by the HyperLynx 8.0 DDRx Wizard t specify the timing requirements at bth ends fr the interfacing signals. The DDRx Wizard uses the parameters frm the timing mdels fr deriving the final timing margins. These timing parameters include skew, delay, setup and hld time requirements n signals with respect t their assciated strbe r clck signal. The DRAM timing mdels are quite standardized since the timing specificatins at the DRAMs are specified by the JEDEC standards. n the case f the cntrllers, it is very likely that the timing requirements are different frm vendr t vendr. The default cntrller timing mdels fr each DDRx interface (ddr_ctl.v, ddr2_ctl.v, and ddr3_ctl.v) are included with HyperLynx in the flder such as C:\MentrGraphics\<release>\SDD_HME\hyperlynx\Libs. These default timing mdels can be used t perfrm simulatins using the DDRx Wizard quickly. f yur cntrller s timing parameters differ significantly frm the default mdel, yu will need t create yur wn mdel t btain the accurate timing simulatin results. T help yu with this prcess, HyperLynx includes the HyperLynx Timing Mdel Wizard and the HyperLynx Timing Mdel Editr. The HyperLynx Timing Mdel Wizard guides yu thrugh the prcess f creating the timing mdel. The HyperLynx Timing Mdel Editr allws yu t edit, check fr syntax, and view the timing relatinships in the frm f timing diagrams. n this applicatin nte, firstly the DDRx timing relatinships in each signal grup are reviewed. Secndly, it defines and explains the timing parameters that are required by the DDRx Wizard at the cntrller. Thirdly, it prvides guidance n hw t find the relevant timing parameters frm three different cntrller datasheets and translate them int the required DDRx Wizard cntrller parameters. Finally, it shws the methdlgy fr creating the cntrller timing mdel by entering thse parameters in the HyperLynx Timing Mdel Wizard (GU based) r in the HyperLynx Timing Mdel Editr (syntax-based). 2.0 Review n DDRx n Timing Relatinships This sectin reviews the DDRx specific timing relatinships between signals at the cntrller during read and write peratins. n the DDRx memry interface, there are fur main grups f signals: Address and Cmmand Signals (A[15:0], BA[2:0], RAS#, CAS# & WE#) Cntrl Signals (CS[3:0], E[3:0], & DT[3:0]) Data, Data Mask, and Strbe signals (DQ[63:0], DM[8:0], CB[7:0], DQS/#DQS[8:0]) Clck Signals (/#[5:0])
2 First, the perating frequency f the clck signal must be determined. The DDRx interface is usually specified by ntatin DDRx <speed-grade>, fr example DDR-400, DDR2-533 r DDR The speed-grade unit is in MT/s (mega-transfer per secnd). n this applicatin nte, DDR3-800 will be used as an example thrughut. n this case, the speed-grade is 800MT/s, and the perating frequency is half f the speed-grade; 400MHz. The bit perid fr address/cmmand/cntrl and data signals is needed infrmatin. The address, cmmand and cntrl signals are utput nly signals but are used fr bth read and write peratins. The address, cmmand and cntrl signals reference an assciated clck () signal. 1T r 2T timing is allwed n address and cmmand signals but nly 1T timing is allwed n cntrl signals. Typically, the cntrller utputs these signals apprximately aligned with a falling clck edge. T achieve this, the address/cmmand/cntrl signal is launched half the clck perid earlier than the clck. This timing is referred t as 1T timing. Fr 2T timing, the address /cmmand signal is launched ne and a half perid earlier than the clck s that there is mre setup time at the receiver. S, the shrtest available setup time fr the address signal fr 1T timing is ne clck perid and fr 2T timing, it is 2 clck perids. Figure 1 is the timing diagram shwing the timing relatinships explained abve. The gray windws are the uncertainties that need t be accunted fr in the real peratin. Figure 1: DDRx Address, Cmmand, and Cntrl Signal Timing at the Cntrller 0ps 1ns 2ns 3ns 4ns 5ns 6ns t 400MHz 1T Prelaunch Delay(max) 1T Prelaunch Delay (min) A/CMD/CTL (1T) [15..0] 1T Bit Perid A/CMD (2T) [15..0] 2T Prelaunch Delay (max) 2T Prelaunch Delay (min) 2T Bit Perid The data, data mask and strbe signals are bi-directinal signals: utputs during the write peratin and inputs n the read peratin. Each data byte lane references a DQS signal. During the write peratin, DQ and DM signals are launched a quarter f the clck perid earlier than the DQS signal fr each byte lane s that bth rising and falling edges f the strbe are centered in the valid data bit windw. Since the data and data mask signals can be clcked in at every strbe edge, the bit perid fr these signals is half f the clck perid. Figure 2 shws the abve described timing relatinship. The gray windws are the uncertainties that need t be accunted fr in real peratin.

3 During the write peratin, the cntrller als needs t meet the delay timing relatinship between the clck signals () and strbe signals (DQS). This relatinship is defined in Figure 3. Figure 3: DDRx and DQS Timing at the Cntrller 1ns 1.5ns 2ns 2.5ns 3ns 3.5ns t DQS 400MHz Delay t (min) Delay t (max) During the read peratin, the DRAMs send bth DQ signals and DQS signals t the cntrller, edge aligned. At the cntrller, these signals must meet certain setup and hld requirements. The setup and hld requirements at the cntrller can be specified in tw ways: at the pins r at the internal registers. f the timing requirements are at the pins, DQ/DM signals and DQS signals are edge aligned. f the timing requirements are specified at the internal registers, infrmatin n hw the cntrller captures the data internally is needed. Typically, the ideal phase shift is ne quarter f the clck cycle. Figure 4 shws the abve described timing relatinships.

The same parameters are als required if yu want t create a cntrller mdel using the HyperLynx Timing Mdel Wizard. 3.1 tac(min) and tac(max) Applicable t address (A) and cmmand signals (BA, RAS, CAS, and WE) n bth read and write cycles

The cntrller captures the DQ signals by typically phase shifting the DQS signal internally by abut 1/4 clck perid. Specify whether the "setup" and "hld" parameters are measured at the cntrller pins (phase shift=0) (Figure 10) r after an internal 90 phase shift (Figure 11). Setup values are psitive if DQ must be valid befre DQS (negative if after); Hld values are psitive if DQ must remain valid until after DQS (negative if befre). Figure 10: tds and tdh with 0 Phase Shift Figure 11: tds and tdh with 90 Phase Shift 4.0 nterpreting and Deriving Required Timing Parameters frm Datasheet n this sectin, three examples are shwn in deriving the HyperLynx DDRx required parameters frm the datasheet parameters. These derivatins are required since each chip vendr specifies the timing parameters fr the cntrller in different ways. Sme f the variatins are: Specified either at the internal registers r at the pin-pad Specified as a skew r as a valid windw Relative t a clck/strbe rising r falling edge 4.1 Example 1: The HyperLynx Default ddr3_ctl Cntrller Mdel n the default cntrller mdel, ddr3_ctl.v, the parameters shwn in Table 2 were assumed t be defined in the cntrller datasheet and Figure 12 shws the timing diagram f these parameters.

10 MPC8544E utput Timing Parameters (Cnt.) Deriving tac(min) and tac(max) fr MPC8544E Figure 17 and Figure 18 shws that the needed timing parameters t derive tac(min)/(max) are tddkhas and tddkhax. n this derivatin, the 533MHz case will be used. Nte that the 533MHz in this case is nt the frequency f the clck but it is rather the speed grade fr the DDRx interface. The actual frequency f the clck is half f 533MHz which is equal t 267MHz. Frm the definitin f tddkhas and tddkhax, they are specified as utput setup and hld parameters. As yu will recall frm sectin 3.1, tac(min) and tac(max) parameters are defined as delay between the address and cmmand utput signals, transitining t "valid" befre the rising edge f the utput clck. Figure 19 shws the relatinship between the DDRx Wizard needed parameters tac(min)/(max) and the datasheet parameters (tddkhas and tddkhax). Table 9 shws the needed derivatins.

As yu can see in the Ntes 2 f Figure 24, tdskew = (T/4 abs(tcskew)). This gives yu a clue that DQS is shifted by t/4 with relative t DQ.

22 5.2 Creating Multi-Speed-grade Timing Mdel This sectin describes the methdlgy t create a multi speed-grade mdel by cmbining the single speedgrade mdels created by the Timing Mdel Wizard frm the previus sectin and adding additinal simple syntax t the mdel. Figure 35: Syntax fr Simple Multi Speed-grade Chipset Cntrller Mdel Figure 35 shws the required syntax fr that multi-grade mdel and the methdlgy t create this mdel is as fllws: 1. Create a mdel fr each speed-grade using the Timing Mdel Wizard as described in the previus sectin. n this example, there are three speed grades mdel files with the names: DDR2_667.v, DDR3_800.v, and DDR3_1066.v. 2. pen the first speed-grade mdel (DDR2_667.v ) in the HyperLynx Timing Mdel Editr. 3. Save this file as DDRx_multigrade.v. 4. n the line after specify, enter `ifdef DDR2_ At the end f `ifdef sectin, enter `elsif DDR3_ pen the secnd speed-grade mdel (DDR3_800.v), and cpy all the lines that are between specify and endspecify. 7. Paste it in the DDRx_multigrade.v file after the line `elsif DDR3_ At the end f `elsif sectin enter `else `define DDR3_ pen the third speed-grade mdel (DDR3_1066.v), and cpy all the lines that are between specify and endspecify. 10. Paste it in the DDRx_multigrade.v file after the line `else `define DDR3_1066
23 11. At the end f `else `define sectin, type in `endif 12. Chse Build > Cmpile t check fr any syntax errrs. Please refer t the BardSim Help Manual in Cncepts and Reference Guide > File Specificatins > HyperLynx Timing Mdel Frmat > "Detailed Syntax - HyperLynx Timing Mdels" sectin fr descriptin f the syntax in mre details. 5.3 Creating a Cntrller Timing Mdel Syntactically n this sectin, the same chipset cntrller mdel is created by entering the syntax directly in the HyperLynx Timing mdel Editr. Since sme f the syntax is cmmn t all mdels, a default cntrller mdel can be used as a starting pint fr this mdel creatin methdlgy Define Tp-level Mdule and HyperLynx Standard Prt Names The tp level mdule and standard HyperLynx prt names are defined in this sectin. The mdule name can be arbitrary but the prt names are reserved fr HyperLynx as defined in the embedded table in Figure 36. This sectin is required in the HyperLynx timing mdel. Figure 36: Syntax fr Defining Tp-level Mdule and HyperLynx Standard Prt Names Specify Chipset Cntrller Datasheet Parameters by Speed-grade n this sectin, the parameters f different speed-grades are entered exactly as defined in the datasheet.

This sectin is respnsible fr prviding the min and max delay values, and setup and hld values between prts t the DDRx Wizard. All cntrller timing mdels must include this sectin and Figure 39 shws the required syntax fr each parameter. The $delay functin is a nn-verilg cnstruct added t the HyperLynx timing mdel syntax. The fllwing is the syntax t specify delay relatinship between tw mdule prts: $delay(frmprt_event, tprt_event, min_delay, max_delay); Fr example, in Figure 39, the syntax $delay(psedge ck, addr_cmd, tacmin, tacmax); sends the min and max delay values (tacmin and tacmax) between the ck and addr_cmd prts t the DDRx Wizard. Remember that the values tacmin and tacmax were defined in
25 the previus sectin. The parameter names are arbitrary but it is recmmended that the standard parameter names (as required by the DDRx Wizard) are used fr purpse f clarity. Nte that parameter tdqdqs and parameters tds/tdh are cmplementary methds f describing the DQ-t- DQS timings during read cycles; nly ne f the tw methds shuld be specified in the timing mdel file. Please refer t HyperLynx Help fr mre infrmatin. Figure 39: Syntax t Define Timing Relatinships This chipset cntrller timing mdel can be dwnladed frm the link in the fllwing tech nte: 6 Summary This applicatin nte prvided necessary infrmatin needed t create a cntrller HyperLynx timing mdel frm a vendr s datasheet. Three examples f different cntrller types were used t describe the mdel creatin prcess. n rder t create these mdels, it is imprtant that the datasheet parameters are translated int the HyperLynx required parameters crrectly. nce the parameters are translated crrectly, the mdel can be created using the HyperLynx Timing Mdel Wizard (GU-based) r using the HyperLynx Timing Editr (Syntax-based). A less rbust cntrller timing mdel can be created quickly and easily using the Timing mdel wizard r a mre rbust mdel can be created syntactically.
