M1 Logiblox: Error - Bus Conflicts during Foundation simulation


Keywords: Logiblox, Foundation, functional simulation

Urgency: Standard

General Description: When doing a functional simulation in
Foundation with a logiblox generated multiplexer, a window
pops up during simulation titled 'Bus Conflicts'.


This is currently a known issue with the Foundation logic
simulator and the warning message that is generated can be
safely ignored.

When a Logiblox MUX is generated with more than four inputs,
the default is to implement the MUX using tri-state buffers.
The simulator has problems interpreting the buffers and
generates the Bus Conflicts error.

There is currently two work-arounds available.

1) Ignore the warnings that pop up. Click on Cancel.

2) When generating the MUX in Logiblox, choose 'Normal Gates'
as the Style. This will not be as efficient as using
tri-state buffers, but will eliminate the warnings.
