2015.4 Zynq BFM - Zynq BFM hangs when sending a set of WRITE BURSTs on ACP Port


I have connected an AXI4 BFM master through an interconnect to a Zynq PS7 ACP port. I am writing 3 sets of different length bursts to the Zynq BFM through the ACP port to the DDR in the simulation.

However, during the 2nd burst, I receive the following error:

[84150] : bfm_dsgn_cdn_axi_bfm_0_1 : *ERROR : RECEIVE_WRITE_RESPONSE Task TIMEOUT - TASK timed out waiting for a WRITE RESPONSE transfer with the id = 0x0

The Zynq BFM does not seem to respond to the last WRITE in the 2nd burst, so the simulation hangs.


This is a known issue with the Zynq BFM.

Please use the attached file which includes the fix.

The fix will also be added in a future release.
