1 Advanced Design System Release 2005A New Features
2 2005A: Focus on Simulation Technology Improvements 2005A Delivers Faster, Smarter, Stronger Simulators: DC simulator Harmonic Balance simulator Momentum 3D-Planar EM simulator Solves previously unsolvable problems without compromising accuracy or requiring designs to be simplified.
3 DC Simulation 2005A Goals for DC Simulator Improvements: Converge 100% of the time with the default setting. Dramatic speed-up with the default setting. Greatly improve DC extracted view simulation capability.
4 DC Benchmark Suite Results Tough Suite: 82 very tough circuits 2004A: 94% convergence 2005A: 100% convergence Huge Suite: A suite of 3150 circuits 2005A: 100% convergence with default settings Speed-up (cumulative run time of the entire suite): 2004A: 350 minutes 2005A: 55 minutes (6.4X)
5 Harmonic Balance Simulation The HB engine is the key simulator in ADS. HB is at the heart of many analyses: single-point HB, oscillator analysis & noise, LSSP, swept HB, envelope, Xdb, HB noise, optimization, yield. Improving HB improves your design flow and overall experience with ADS.
6 Harmonic Balance Simulation Existing HB solver Improve HB engine robustness and speed at its default settings. Users may have to tweak settings to achieve convergence and optimal performance. 2005A goals > 90% convergence with default setting. Near optimal speed with default setting. Improved HB setup usability.
7 HB Results: Robustness Benchmark suite size of 381 circuits: 2004A: 40 Non-converging 2005A with default settings: 22 Non-converging (93% convergence) 2005A with user-tweaking: 10 Non-converging
8 HB Results: Speed Harmonic Balance Test Suite of 381 circuits. Average speed-up versus 2004A: 5X. Large/difficult circuits that took >10 minutes in 2004A had a cumulative speed-up of 7X. All 8 circuits with >1000 transistors converged. 2005A cumulative time with default settings beat 2004A time with optimized settings.
9 HB Results: Speed Cumulative run times: Benchmark suite with user-tweaked settings: 2004A: 4.22 hrs (Time spent in finding the tweaked settings not accounted for.) Benchmark suite with default settings: 2005A: 3.96 hrs (1.06 X)
10 Harmonic Balance Simulation Easy-to-Use Excellent results with default (auto mode) settings. Intuitive terms for parameter settings. Full access to simulation parameters still available.
11 2005A: Focus on Simulation Technology Improvements 2005A Delivers Faster, Smarter, Stronger Simulators: Faster: average 8X faster for DC, 5-7X for Harmonic Balance. Smarter: built-in intelligence reduces simulation setup time. 100% DC Convergence with default settings. 90% HB Convergence with default settings. Stronger: large circuits with thousands of transistors and >250K parasitics have been successfully simulated with DC and Harmonic Balance.
12 Momentum Improvements Improved Thick-Conductor modeling. New Iterative Matrix solver. New 64-bit engine.
13 Improved Thick-Conductor Modeling Accurate simulation of thick conductors: Phase I (2003C) automatic 3D expansion for thick conductors. Phase II (2004A) improved surface impedance loss model. Phase III (2005A) horizontal currents on side walls. T W As thickness/width aspect ratios increase, horizontal currents must be included for accurate simulation.
14 Example: Silicon Spiral Inductor 3 um 5 um 4 um σ=3.33e7 S/m AIR 500 um Silicon: 11.9, σ=6.66 S/m GND Spiral windings Width = 15 um Separation distance = 5 um Thickness metallization = 4 um Guard ring with substrate contacts
15 Edge Mesh OFF No Side Currents Matrix size: 421 Frequency points: 10 Total simulation time: 17s Silicon Spiral Inductor 2004A Measurements vs. Momentum Fast, but less accurate.
16 Edge Mesh ON No Side Currents Matrix size: 2287 Frequency points: 10 Total simulation time: 8m15s Silicon Spiral Inductor 2004A Measurements vs. Momentum Accurate, but slower.
17 Silicon Spiral Inductor 2005A Edge Mesh OFF Side Currents ON Matrix size: 667 Frequency points: 10 Total simulation time: 19s Measurements vs. Momentum Fast and accurate.
18 Silicon Spiral Inductor 2005A Edge Mesh ON Side Currents ON Matrix size: 4055 Frequency points: 10 Total simulation time: 15m33s Measurements vs. Momentum More accurate, but much slower.
19 New Iterative Matrix Solver Analogous to Krylov Matrix Solver for Harmonic Balance Simulations. Simulation time proportional to number of unknown currents squared versus cubed for the Direct Solver. Momentum automatically chooses the best solver to use for you. Simulation time ~ O(N^3) O(N^2) Unknown currents (N)
20 LTCC Filter with 9 Filter Sections Settings: edge mesh, 30 cells/λ Simulation results (0 6 GHz) Statistics: # Freq. Points Matrix size Matrix load time Matrix solve time Total Simulatio n time 2004A m23s 18s 12m15s 2005A s 1-3s (*) 2m38s (*) new iterative solver PIV 3 GHz, Linux WS3.0 Accurate and faster simulation.
21 Momentum64 Example unknowns not possible on a 32-bit machine Current Visualization of a Patch Array at 9.5 GHz. Typically only 1 to 4 patches could be simulated in the past bit Momentum Engine provided with 32-bit CDs. - Remote simulation to Linux and UNIX machines.
22 Momentum Improvements Momentum Improvements Accurate thick-metal modeling due to available horizontal side-current modeling. New iterative solver allows simulation of larger problems such as packages or larger PCBs faster. New 64-bit version of Momentum engine (separate installation) allows simulation of large problems not possible before.
23 Gerber-Union Import/Export Reads multiple Gerber files into a single database. Exports entire image, or selected area. Exports multi-layer EGS Archive, suitable for import to ADS. Works w/gerber files from any board/module-level layout tool. Model number E8917. Contourizes Gerber vector data into polygons.
24 Agilent & CST Alliance Mutually Exclusive Alliance focuses on integrating CST s technology-leading 3D EM Simulation into the Agilent ADS Design flow. Ability to simulate fully 3D EM applications like Signal Integrity, packaging, and RF module design within the ADS design flow. Integrated capabilities simplify the design flow and speed characterization of wireless and wireline designs.
25 Printer UI and Support Improved Printer UI and new Printers Currently targeting support of HP DeskJet 970C & 800PS, HP LaserJet 4000/5000/8000 series of color printers. Export color graphics to PostScript on UNIX. Windows-like printer UI. Export of JPG, BMP, GIF formats for use in Windows tools (Word, Excel, etc.). Print All command.
26 Many Other Improvements Smith Chart and Matching Utilities Now Included in PDE. Vastly improved layout redraw speed.
27 Many Other Improvements Library browser highlights new libraries. Budget Analysis now includes non- 50 ohm TOI and SOI measurements. Mixer component includes nonlinear characteristics. Easier mechanism to select and move markers.
28 Many Other Improvements More content in the Schematic Wizard More application types. More simulation types. Error catching, even when not using the Wizard.
29 Design Guide Updates Mixer Design Guide Adds other frequency translation devices (multipliers, dividers, etc.). Filter, Smith Chart, and Matching Design Guides Have a more consistent UI for source and load impedances. Passive Circuit Design Guide Improved interdigital, combline, hairpin and edgecoupled filter designs, plus new attenuator.
30 New DDS FrontPanel Instrument-like display. Can be saved as a standard DDS display, which provides access to equations. Easy to use. Eye-diagram.
