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
