Hi,
I’m currently using the UVVM SPI VVC in my verification environment.
In my testbench, I configured the VVC with the following generics:
GC_DATA_ARRAY_WIDTH => 1523
However, when I try to send 229 bytes of data using the v_cmd.data field in the test case, only 31 bytes are actually transmitted. The remaining bytes are replaced with ‘X’.
After debugging the issue, I realized that the root cause is the following constant defined in the adaptations_pkg:
constant C_SPI_VVC_DATA_ARRAY_WIDTH : natural := 31;
This constant appears to limit the usable width of v_cmd.data, even though I configured a higher width via the generic.
My question is: Is the only way to fix this problem by manually modifying the adaptation_pkg and increasing the value of C_SPI_VVC_DATA_ARRAY_WIDTH?
Or is there a better way to propagate the value from the VVC generic to avoid this mismatch?
Thanks in advance.
