AR# 6607
FPGA Express 2.x,3.x: Express hangs while checking syntax (Abort at 1704)
Description
Keywords: FPGA Express, hang, syntax, Foundation
Urgency: Standard
General Description: When attempting to check syntax of a HDL design in Foundation or in standalone FPGA Express, the software hangs. No error message is reported, and the machine has to be rebooted.
Sometimes, the following error message is reported: Synopsys Internal Error: Abort at 1704
Solution
Check to see if the application DDP32 is running. If so, then it must be stopped before using Express. The DDP32 application is a virus protection application that has a conflict with FPGA Express.
