layoutXL update components and nets

[Erik Wanta]

I have 2 resistors in a schematic connected with 2 nets (a and b). I
run layoutXL and connectivity->update->components and nets and it
brings in the resistors. I connect the resistors up and see that the
nets have connectivity a and b. In the schematic, I change net b to
net c and again run connectivity->update->components and nets in the
layout. I was expecting the connectivity for trace b to change to net
c, but it stayed as net b. Why doesn't
connectivity->update->components and nets update the connectivity?

Hi Erik,

A typical VXL problem. Your best bet is to delete the resitor in question
and re-create it with vxl. This goes along with the confusion stuff I
mentioned in theother thread. VXL is great, but it takes a while to learn
its tricks. It can definetly lie to you!

VXL tricks sounds like VXL bugs. Why isn't it called
connectivity->update->components instead of
connectivity->update->components AND nets? In what way are the nets
updated?

Sounds like a bug to me.
