AR# 7794
FPGA Editor 2.1i CS2 - Selecting a Path in the List window does not select the path in the Array window.
Description
Keywords: FPGA, Editor, path, from, to, list
Urgency: Standard
General Description: When I select a path under "PATHS" in the List Window, nothing is selected in the Array (main) window.
Solution
FPGA_Editor analyzes all of the constraints in the PCF, including TIGs. If the selected path has a TIG associated with it in the PCF, and none of the paths specified by the TIG are covered for timing analysis. Consequently, no paths are displayed in the Array Window.
Also, if the path only has BELs (Basic Elements), and no comps, macro instances, or nets in it, then nothing is displayed when it is selected from the list.
