  "message": "Force URAM Usage for ML and SMC Memories\n\nBRAM utilization was approximately 90% prior to change. This appeared to\nbe the cause of build failures.\n\nThis change effectively change targets large u_ram1p_ram_smc and\nu_ml_dmem RAMs and requests the vivado tool to set these to URAM with\nnew synth only constraint (synth.xdc).\n\nLouhi build available temporarily here\nhttps://louhi.dev/5958780716318720/execution-detail/4590981286068224\n\nBuild is successful and imp utilization report available in the logs at\nthe above Louhi link shows the following utilization changes:\nURAM utilization increase to ~31% (from ~1%)\nBRAM utilization reduced to ~13% (from ~90%)\n\nChange-Id: Ib9ef26b54815043882adcd644c936a3739e74f62\n",
