9.1i ISE - Project Navigator GUI is unresponsive or slow to respond while processing schematic-based design
Description
Keywords: hang, response, slowness, wait time, IP core
The Project Navigator GUI becomes extremely unresponsive during certain processes.
In a schematic or schematic/core based design, when the Synthesize - XST process is run, a number of sub-processes are run prior to running XST. For a large design containing many schematics and IP cores, the GUI is almost completely unresponsive.
Solution
For each of the schematic or IP core modules in a design, Project Navigator receives multiple GUI messages as the module is processed. The number of messages received cannot be handled by the GUI without causing degradation of response time.
