Problem Description:
Keywords: Express Mode, XC4000EX, XC4000XL CRC

Urgency: Hot

General Description:

When using XC4000EX/XC4000XL Express Mode, CRC must be disabled.  This

the bitstream.


Solution 1:

To specify Express Mode, go into Template Manager (Utilities in Design
Manager) and modify or create a new configuration template.  Go to the
Customize screen and add the following option:

   Program Name:     bitgen
   Program Options:  -g ExpressMode:Enable

To specify Express Mode, from the Design Manager menu, select
Utilities->Template Manager.  In the Template Manager:

   Select - Configuration Templates
   Select - <Family Type>
   Select - Customize

In the Customize dialog:

   For Program Name enter:     bitgen
   For Program Options enter:  -g ExpressMode:Enable
   Click - Set
   Click - OK

In the Options dialog, make sure that the Configuration template
that you customized is selected.  When the configuration step is run,
the -g ExpressMode:Enabled option will be passed to the bitgen command.
