Mentor Graphics: PLD_DA: How to enter a TIG constraint
Problem Description:
Urgency: Standard
General Description: This solution describes the method to place a TIG (Timing Ignore) property on a
Mentor Design
Architect schematic net in order to tell the M1 tools to ignore
this path for timing driven placement and routing.
Solution 1:
To add a TIG constraint to a net:
1) Select the net. Make sure the vertex where the output of a
symbol connects to the net. Be sure you have selected only
that vertex; a single star should appear at that location.
2) Press the right mouse button.
The Net popup menu will appear if you have selected a
net or a pin.
3) Select the Properties -> Add -> Add Single Property
command from the popup menu. The Add Property dialog box
appears
4) In the Property Name box, type TIG
5) If the TIG property is to be applied globally to the
design, leave the Property Value box empty. Otherwise,
Type in the TS identifier to be ignored in the Property
Value box.
6) Select String in the Property Type field and Select OK.
