Title
Error: Cannot start the command line quartus_map
Description
You may see this error in the Quartus® II software version 9.1 SP1, when Parallel Synthesis is enabled and multiple processors are allowed during compilation. The Quartus II software creates child processes to compile a design partition when Parallel Synthesis is enabled. This error may occur when a child process is not created successfully because the Operating System (OS) has a full process table or has exhausted a required resource.
To work around this problem in the Quartus II software version 9.1 SP1, follow the steps below:
- On the Assignments menu select Settings to open the Settings window.
- Select the Analysis & Synthesis Settings Category.
- Click More Settings...
- Turn off Parallel Synthesis
This problem is scheduled to be fixed in a future release of the Quartus II software.
