Genus supposedly has better correlation with PnR and Timing tools from Cadence, as some of the engines that are used in those tools are used over here in Genus. 1: New Architectural Compiler Technology Delivers the Best PPA for Advanced IP. , class declaration, @(posedge )), and some errors about attributes which in this case, after reading a bit about, I ignored when they were warnings or deleted when they were Optimizations in Synthesis # (Note: All the commands reference in this document is related to Design Compiler) Optimization Phases ; The optimization process modifies the logic in a netlist. You switched accounts on another tab or window. The command to report congestion in Genus is “report_congestion”. We had Followed guidelines of the Genus Flow. Please note that these results are grouped in path groups, not by clocks. Genus Command. Genus Synthesis Solution GUI (Graphical User Interface) helps you view and highlight the instances and timing results to better explore/debug your design. 5. I've included options to make it easy to read in a large number of HDL files. From there run the script with the command <code>source <script_name>. Fig. It checks the syntax and UI with Cadence’s Genus™ Synthesis Solution and the Tempus Timing Signoff Solution. This lab uses the following software: GENUS 17. Say tech1.

If you have a question you can start a new discussion Cadence Commands: Legacy Vs Stylus CUI mode. Open the conformal using command lec as below: – (execute the following commands in the setup command line) 6. I am getting following errors in check_timing_intent. To do this, start Genus and enter the command <code>set_db common_ui false</code>. This demo explains path grouping concept in Genus Synthesis Solution in Stylus CUI mode. the genus: shell prompt. From this powerful combination, you can gain an up to 10X improvement in RTL design The following is my notes of GENUS training course on Cadence’s training module. Commands. Further, it will show you how to do analysis in GUI mode of Genus Synthesis Solution to trace back the fanin cone of the flops clock pin to find about the clock gating instances. Understanding Clock Gating Report and Cells. I use Synopsys DC. I have also written the SDC constraints for the I/O ports.
