| _florent_ | lkcl: hi, have you been able to do tests with the simplified targets i provided you? The aim was first to get basic design working without DRAM, because i was expecting it to cause troubles at the frequencies that can be achieved with the current version of your CPU. | 07:28 |
| _florent_ | if you want to remove the DRAM from the design, you can add --integrated-main-ram-size=0x1000 to the command line | 07:30 |
| _florent_ | i would first recommend getting this working in a first time, for the DRAM, it's currently synchronous to the CPU, so this will indeed cause troubles with the frequencies you are targeting, we could have a mechanism to decouple that, but it's not currently in place since hasn't been useful in the past | 07:34 |

| lkcl | _florent_, i am using them, yes. | 08:39 |
| lkcl | yes we really need the DRAM clock decoupled. there is a Broadcast Bus with over 20x 64-bit INT registers accessing the Regfile Read port | 08:41 |
| lkcl | the MUX tree that is created is so large that it results in massive routing and there's unlikely to be any way that i can get the speed even above 48mhz as a result | 08:42 |
