Record #3466

Product Family:  Software

Product Line:  FPGA Implementation

Problem Title:
M1 Constraints/UCF/TRCE: How fine can the resolution be on timing
constraints?



Problem Description:

Keywords: timing, constraints, UCF, TRCE, resolution, nanoseconds, picoseconds.

Urgency: Standard

General Description:

How fine can the resolution be when entering timing constraints (e.g. nanosecond
s, picoseconds)?


Solution 1:


TRCE only operates on and reports timing constraints down to picoseconds, or tho
usandths of nanoseconds.
