I'm VoltageStormPE user. Frankly speaking VoltageStormPEdemand DEF, LEF and PowerReport in the view of design data.Now we are about to move into EPS.EPS seems to demand DEF,LEF,PowerReport as well as verilog,SPEFeven I don't need to execute power calculation.Can I execute EPS without verilog,SPEF as substituion of VoltageStormPE.
Hi, EPS will need about the same inputs as VSPE. If you have an Encounter database, most of the data is already loaded when you go into EPS. We do need the SPEF and Verilog for power calculation, not for rail analysis.
You can also run the older VoltageStorm flow from the EPS tree, if you want to keep your old flow or do not have an Encounter database.
EPS is at it's best when you are running Encounter, since EPS can read the database directly. The Verilog, liberty files, sdc, etc, will already be loaded into Encounter.
Hi Thank for your comment.
I'm afraid I'm VoltageStorm user, not encounter user. I guess eps would be modified for new usefull function and refinement of existing function. On the other hand I assume voltagestorm wouldn't be modified any more, so I prefer eps to voltagestorm.
Are there any option or command that make eps skip reading verilog, sdc procedure.I just want to analyze IR drop and EM with DEF, LEF, GDSII without verilog, spef, sdc.
Hi, you can still run VoltageStorm as always, the binaries are included with EPS.
Most of the new features added to EPS will require you to have the data loaded into EPS. These are not available in the older Vstorm flows. We added a lot of debugging features, like a violation borwser, resistance path tracing, more plots, etc. These all depend on data being loaded into EPS.
I would recommend trying to move to EPS and supplying the required data, this will get you the best features.
Hi Thanks for your comment.
I'll move into EPS to make best use of new feature.
