When generating Async FIFO v5.1 core, you might see following issues:
1. The Async FIFO depth always defaults to 15, regardless of the value selected in the GUI. You can verify this by opening the "<component_name>.v" or ".vhd" template files produced by CORE Generator.
2. For the Async FIFO with "type= Dist Mem", core generation will hang and the CORE Generator process must be killed to recover.
The above two issues are caused if you have downloaded the 61i_ip_update1during the month of December 2003.
Please download the new version of the IP update available as of Jan 9, 2004 (61i_ip_update1_01) from:
The new IP update can be installed over the previous version without un-installing any of the previous update files. Asynchronous FIFO v5.1 core generated with the previous update will have to be re-generated with this newer IP update.
