Problem Title:
QuickSim: Mode pins (MDO, MD1, MD2) cannot be used in board-level
simulation.



Problem Description:
Keywords: mode pins, MD0, MD1, MD2, board-level, pads

Urgency: Standard

General Description:

A board level simulation of a design that contains mode pins (MD0, MD1,
MD2) will not accept any force to the nets connected to these pins.  The
waveform will only show strong contention on the signals.


Solution 1:

The only workaround is to remove the mode pins from the design and replace
them with standard I/O pads.
