Problem Title:
M1.5i/2.1i: What are the resources that needs to be constrained in the user constraint file?


Problem Description:
Keywords; resoureces, constraints, M1.5

Urgency: Standard

General Description:
What are the resources that needs to be constrained in the user
constraint file (M1.5)?


Solution 1:

The resources that needs to be constrained in the user constraint
file are as follow:
1) The internal signal for one or more clocks.
2) I/O speed.
3) Logic using multi-cycle clocks.
4) Pin to pin timing.
5) Pin locations & logic locations.
