adding connectivity to metal

Hello,

I have a layout which was done for me by a layout person who for some
wierd reason didn't use VXL for the entire time. The result is when I
click a piece of metal and query it, it more often than not does not
have connectivity information. Also there are places where there is,
but it is wrong (probably from copying a piece of metal in virtuoso,
not virtuoso-XL).

Is there an easy way to have VXL go through a layout and fix the
connectivity information on all the metal?

Without this, it takes me much longer trying to review parts of a
layout when I have to start tracing wires around to figure out which
net it is part of.

Thanks

Hi Dan,

Have you tried Connectivity->Update->Components and Nets from your VXL
layout?

 

In order for Connectivity->Update->Components and Nets to work
properly make sure the "Instance Names" of the devices/cells/pcells
match to the schematic. (EX: If the schematic symbol is M1 the layout
should be |M1) << the layout needs the "|" pipe character.

If the Connectivity->Update->Components and Nets changes the inst
names of the layout components, adds "_old" to the names undo it or
start again and turn the "update instances" button off on the VXL
options menu. It will add the _old if the cells don't come from the
VXL expected library.

Good Luck,
Tim
