Re: Importing cell library into Electric 7.00

[Ming Deng]

Thanks Steve for your answer.

After some tweaks, I was able to import LEF/DEF into Electric 7.00. Here 
was what I did:
1. In LEF, renamed all layers to be in the formats of "POLYn", "METALn", 
"VIAn" or "CONTn". (n is a number here)
2. In DEF, added width information for special nets VSS and VDD. ( + 
ROUTED layer_name width )

Basic layer information of each cell were successfully imported into 
Electric. But all net names were lost.
