Problem Title:
Quicksim II: No-connects appear on Fncsim8-created schematic containing
XBLOX
Problem Description:
When you run Fncsim8 -o (use original schematic) on a design that contains
XBLOX components, Fncsim8 generates a simulation model that looks similar
to your original schematic in a component called simdir/design_name. If
the original schematic has any pin vertices connected by a zero-length net
(i.e., has any pin vertices laying on top of each other), the "clone"
schematic shows no-connects (those circle-with-the-slash-in-the-middle
symbols) on these vertices. The no-connects occur in any location where
there are two vertices laying on top of each other in the new, generated
schematic.
Solution 1:
The best solution to this problem is to go back to the original schematic
and move any coincident vertices apart, so that you can see the net between
them.
Solution 2:
You can open the simdir/design in pld_da and do a Connect -> Connect All
(from the right-mouse-button pop-up menu) then a Check and Save on each
sheet. Then rerun pld_dve_sim simdir/design before rerunning Quicksim.
