I am going to create ICT file. I have all the documents about creating ICT. What I am wondering about is how I can extract the data needed in ICT file. Are there any other files that I should look the get the data needed in ICT file?
Hi yazdanDepending on the complexity of the ictfile which you are trying to create, it might not be possible to obtain all the data. E.g. ictfiles for 90nm and below should preferably have WEE (wire edge enlargement) and erosion tables but it is not possible to find such data in DRC manuals or Virtuoso techfiles.For a simple ictifle which only requires min_spaciing, min_width and resistivity information, you should most probably be able to find the information from the foundry documents or make some guesses from Virtuoso techfile, DRC and LVS rules files.Best regardsQuek
Thanks Quek for reply.
Actually, I am going to do power analysis. Do you have any idea whether I need every detail in the ict file.
Hi yazdanThe key lies in the process node which you are using. If it is 90nm and below, then you would need those data (wee, erosion, etc) in order to have accurate RC extraction. May I know the process node which you are using?ThanksQuek
It's 90nm. I am completely new to soc encounter. I have dought that we have the complete library in our university. Is there any other way for that? I think our library is just academic (I'm not sure)
Hi yazdanI think perhaps it might not be necessary for you to create the ictfile. QRC extraction requires a "qrcTechFile" which is the output of simulation using an ictfile. Perhaps it might be good to go to the pdk directory and execute the following cmd:terminal>find ./* -name "qrcTechFile"Best regardsQuek
