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