Problem Title:

2.1i Virtex Map - ERROR:basmm:227 - LUT2 symbol "G_6919" (output signal=N_8071) has an equation..



Problem Description:
Urgency: Standard

Problem Description:
Design run through generates the above error in MAP. Why?


Solution 1:

This error is caused when some driver-less signals being trimmed away by
map which leaves the LUT inputs undriven.

Run the design through MAP again with trimming disabled (-u switch) to
examine the result in FPGA Editor to determine the cause of the sourceless
nets causing the problem.
