Hi Aravind, I suspect the issue lies with your snap shot (accum0_snap_ss) - it is 64 bits wide now and the others are 32 bit. You are probably using a version of the toolflow and xml2vhdl repo that does not support asymmetric bram usage - I just confirmed that. I would suggest you verify this, by installing the following mlib_devel:
https://github.com/ska-sa/mlib_devel <https://github.com/ska-sa/mlib_devel> (devel branch) You will need to do the following: 1) git clone https://github.com/ska-sa/mlib_devel.git 2) git checkout devel 3) cd <path to>/mlib_devel 4) follow install in https://casper-toolflow.readthedocs.io/en/latest/src/Installing-the-Toolflow.html You will notice there is a pull request on casper-astro/mlib_devel awaiting a review. I will discuss with Jack this evening during our CASPER meeting. Once that is approved then you will be able to use your slx file as is - https://github.com/casper-astro/mlib_devel/pull/123. We were unable to support any BRAM size other than 32 bits originally. I am now pleased to report we can support all sizes again.
