Mismatch issue #52

Closed Nathanat77 closed 3 months ago

Nathanat77 commented 3 months ago

Hi Taichi Ishitani;

I have tried first run with your TVIP-AXI, however I have got the mismatch issue as follows:

UVM_ERROR /net/tvip-axi/sample/env/tvip_axi_sample_write_read_sequence.svh(74) @ 191000: uvm_test_top.master_agent.sequencer@@tvip_axi_sample_write_read_sequence [CMPDATA] write and read data are mismatched !!

The command I used is : make sim_vcs TEST=default

If I forced the setting wstrb in tvip_axi_master_driver.svh to 'hffff as follows, the mismatch is gone. vif.master_cb.wstrb <= 'hffff;

I am wondering that it is bug?

Thank you.

Regards Nathan

Thank you for confirmation. Do you have solution for it?

Thank you.

I'm investigating now.

The memory model includes a bug and I've fixed it. Can you try again?

$ cd tvip-axi
$ rm -rf tue tvip-common
$ ./setup_submodules.sh
$ cd sample/work
$ make RANDOM_SEED=-2081893827 default
