Mentor Graphics Corporation (NASDAQ:MENT) announced that its low power RTL-to-GDSII tool flow has been included in Taiwan Semiconductor Manufacturing Company, Ltd. (TSMC) Reference Flow 10.0. TSMC and Mentor worked together nearly a year to validate and deliver a robust set of tools with proven support for the Unified Power Format (UPF). “In addition to expanding the Mentor reference flow to add both functional verification and implementation technologies, Mentor is addressing new challenges such as low power,” said S.T. Juang, senior director of Design Infrastructure Marketing at TSMC.
The Mentor low power track includes the 0-In® CDC, Questa®, FormalPro[tm] , Olympus-SoC[tm] and TestKompress® tools.
- The 0-In CDC tool provides a three-fold verification approach for clock domain crossings, checking for appropriate synchronization through structural analysis, protocol verification, and accurate simulation of metastability effects.
- The Questa platform enables early verification and evaluation of power architectures starting with RTL, through automatic insertion of power management logic based on UPF specifications. The Questa platform provides silicon-accurate simulation of isolation and retention protocols during power down/up, non-operational bias modes, and dynamic voltage scaling, as well as static and dynamic checks for power management functional correctness that pinpoint any failures to simplify debugging.
- The FormalPro tool verifies the pre- and post-routed netlists against the RTL + UPF specification from which they were derived, to ensure that retention registers, isolation buffers, and level shifters are equivalent, as well as verifying logic equivalence.
- The Olympus-SoC implementation system provides true multi-corner multi-mode (MCMM) optimization of timing, power, signal integrity and die size, and MCMM clock tree synthesis and optimization. The Olympus-SoC system provides UPF hierarchical low power automation with both top-down and bottom-up flows. It also provides a completely automated, multi-voltage flow with support for Dynamic Voltage and Frequency Scaling (DVFS) handles varying supply voltages and clock frequencies, as well as special power-related cells such as level shifters, isolation cells, and MTCMOS switches.
- The TestKompress ATPG tool reduces power dissipation during all phases of scan test using a constant-fill decompressor, which reduces unnecessary logic transitions, and power-aware control of clock gates.
“Mutual customers of Mentor and TSMC continue to push the design envelope to create complex SoCs that require adoption of advanced, low-power technologies,” said John Lenyo, Mentor Graphics functional verification division general manager. “Our collaboration with TSMC gives design teams access to a comprehensive low-power flow that addresses the low-power challenges from design inception to tapeout.”
