Yes, that is the correct fix. The code is now in the repository.

Thanks!

Sorry, it looks like the example that I sent previously works with version 9.05 of Electric, but not with 9.06.

I think the functionality might have been broken slightly by the bias ports fix [ https://java.net/projects/electric/sources/svn/revision/15467 ].

It seems like it might be fixed by changing line 496 in com.sun.electric.tool.erc.ERCAntenna.java [ https://java.net/projects/electric/sources/svn/content/trunk/electric/electric-java/com/sun/electric/tool/erc/ERCAntenna.java?rev=15813 ] from

ret = ERCANTPATHGATE;

to

return ERCANTPATHGATE;

Dr. Rubin, can you confirm if this is the right fix or if different changes are needed?

Hi everyone:

I've tried to force an antenna error in my designs, just to verify if this checking is working well in Electric. I'm using the MOCMOS technology, with 3 layers of metal.

I've making cells with intentionally long layers of poly1 or metal1, connected only to the gates of small MOSFETs. Curiously, when running the Antenna rule check, the software never points any antenna rule violation.

Can anyone explain what I should do to perform this test (preferably to find the errors)? Can anyone send me a cell with an antenna rule violation example?

Thank you.

Estevao
