New page

There's an optional (advanced) interface for indicating when a write completes (along with the ability to send 17 bits of write-complete control data with the write request in order to ID the requests). Use of the interface means the write flush interface is not available.

To enable, edit the main project makefile to set the appropriate environment variable:
export MC_WR_CMP_IF = 1

The ports to the cae_pers module must be modified; the scripts that compile verilog for both the hardware simulator and for building a bitfile will define "MC_WR_CMP_IF" inside of "pdk_fpga_defines.vh".

// Top of file (already included)
`include "pdk_fpga_defines.vh"

// ...

// Part of the cae_pers module port declaration
