Hi ,
What is the difference between Galaxy power, prime rail and PT Px4 tools.What actually will Galaxy power do? Which is best for IR drop analysis. For initial trail IR drop analysis, will Galaxy power is helpful?

Thanks in advance

Apache RedHawk is best for IR Drop analysis.

Hi,
Thanks for the reply. In our company, we are recommended to use synopsys tools. Please can you tell me the difference between galaxy power, prime rail and PT Px4 ?

Thanks

As previous user told, redhawk is quite close to SPICE simulated values. Next comes Encounter Power System (from cadence).

A Big no for Primerail + PTPX combo at this point of time, as we have scenarios where the tool is unable to understand some of CCS constructs in .lib itself.
I hope synopsys fixes it soon.

u can still , get away if u are running static IR drop, but Primerail + PTPX combo is very very pessimestic , u will end up overdesigning your Power Ground Network

Thanks for the useful information.

Hi,

Can PrimeRail be used as a standalone tool and take design data (verilog/def/spef etc) from other P&R tools, like Encounter, and run IR drop analysis?

Or, does it only work with Milkyway design database from ICC?

Thanks,
Ted

The most easiest way would be to create a milkyway database.

if u already have an ICC db , dump it from there.
else if u use another third party PNR tool, take the design data & create a milkyway db.

this would be far easier to setup up the flow & would be more easier to debug, incase of any issue. its better to start with mw db
