6.1i iMPACT - I am unable to select both "Load FPGA" and "Parallel Mode"

Description

Urgency: Hot 

 

General Description: 

In the 6.1i/5.2i iMPACT GUI, I cannot select the PROM options "Load FPGA" and "Parallel Mode" at the same time for the VQ44 and PC44 packages. When I select "Load FPGA", the "Use D4 for CF" option is automatically selected. This is correct for only the SO20 and PC20 packages.

Solution

To work around this problem, manually add the PROM file when iMPACT is first launched (do not use "initialize chain"). If you use initialize chain first when opening iMPACT, you must close and re-open iMPACT, and then manually add the device before the correct option selections are available.
