General Description: When I attempt to run a Synplify or Synplify Pro flow within Project Navigator using either Verilog or VHDL, the synthesis process terminates and reports the following message (even though Synplify completes and produces an EDIF file):
"@E:Internal Error Please call Synplicity Support (USA) at (408) 215-6000 or send an e-mail including this log and test case to firstname.lastname@example.org $ Start of Compile"
This occurs on a machine that is running a Windows XP Pro operating system and Synplify 7.1.
If I run the same file through the Synplify GUI, the design synthesizes without error and produces an EDIF file that can be implemented using the EDIF flow in Project Navigator.
Synplicity has provided the following method for working around this problem:
1. Under Control Panel -> System, select the Advanced tab. 2. Under the "Performance" section, click "Settings...". 3. Select the "Adjust for the best performance" box. This turns off the fading effects, animation, etc.
This issue has also been resolved if "Windows Classic Style" is selected in the Appearance tab of the Display Properties window:
1. Right-click from the desktop and select "Properties". 2. Select the Appearance tab. 3. Choose "Windows Classic Style" for the "Windows and buttons:" selection.
