General Description: In F1.4, when trying to functionally simulate a Sin/Cos Coregen module the simulator may crash with a page fault error: SIMUL caused an invalid page fault in module <unknown> at 000:10001523
The project manager window displays: Simul: ...ns Bus conflict encountered in the following node:...
解决方案
This page fault is caused by the large number or warnings which are attempting to be written to the log screen. The warnings are indicating Bus Conflict Errors, which are caused by the fact that the implementation of the larger Sine/Cosine cores is done using TBUFs, and the simulator flags possible bus conflicts on the outputs of these TBUFs. These warnings can safely be ignored, so the problem may be worked around by turning off the reporting of these messages to the screen.
This can be done by selecting the following menu items:
Options -> Preferences -> Reports Tab
On the Reports Tab, uncheck the Bus Conflict Error classes for Display, Register, and Report.
