Problem in implementing eco on EDI on a legacy database which used another pnr tool

Ramil

Hi,

I was trying to implement an eco on EDI.  The catch is the database I am implementing it on is not created by edi.  I have a full def of the design.  And these are the steps that I  did.

Created a .globals file were the input netlist is the eco netlist.
Created a view_definition file.
Def in the  data using the normal def in command not  the eco defin  because defIn has preserve shape
Delete the filler- deleteFiller -prefix <pre>
Then eco place - ecoPlace
Then eco route - ecoRoute

I am getting an issue when I do an eco route.  Mainly when it is doing the detailed route.  
It has been 3 hours since i started and the design I have is small.  Not sure why it is taking too long.

Please note that the database I am working on came from talus.

Regards,
Ram

  • I discovered the issue.  The database pitch is different from the technology lef pitch.  That is why that  it's taking too long.  You need to apply the pitch of the tech lef on the old database by "generateTracks" command.  After issuing that ecoRoute was able to route the design.
