2.1i FPGA Editor - Path constraint functionality is not supported.

Description

Keywords: path, constraint, functionality,

Urgency: Standard

General Description:
The "Adding the Path Constraints" function is greyed out in FPGA Editor. How do I add a path constraint?

解决方案

Edit the PCF file directly.

The FPGA_Editor should be able to add path constraints directly to the PCF.

The PCF syntax is as follows:

PATH "path_name"= FROM group_item THRU group_item1...
group_itemn TO group_item;
PATH "path_name" MAXDELAY=path_value;

This will be fixed in a future software release.
