| sf-slack2 | <acomodi> @hackerfoo: I have a question on brams: what should be the behavior of the xc7 bram tests on HW? | 13:26 |
|---|---|---|
| sf-slack2 | <acomodi> Meaning, what should I see to be sure they are correctly working? | 13:26 |
| hackerfoo | acomodi: Here's how to run the test: https://github.com/HackerFoo/hackerfoo-go-functions/blob/master/functions/symbiflow#L214 | 13:28 |

| sf-slack2 | <acomodi> @hackerfoo: Great, thanks | 13:29 |
| hackerfoo | If you want, you can install my symbiflow scripts and use "go bram_test 36 run": https://github.com/HackerFoo/hackerfoo-go-functions | 13:32 |
| tpb | Title: GitHub - HackerFoo/hackerfoo-go-functions: HackerFoos go functions (at github.com) | 13:32 |
| sf-slack2 | <acomodi> Yeah, I think that is the best way, and those scripts are very handy actually | 13:33 |
| hackerfoo | I hope others create their own script repos that can be linked in to .go.sh, then the answer to "how do I do this?" can be "run `go something`" instead of sending scripts around. | 13:52 |

| hackerfoo | `go sf_build something`, and then if it fails you can use `go error_command` to show the failed command, or `go retry_error_command` to run just that command again. | 19:30 |
| markus58 | hackerfoo: Thanks I will have a look. Nice to see that there is a 'good first issue' label. | 19:32 |
| markus58 | hackerfoo: So the title of https://github.com/SymbiFlow/yosys/issues/32 looks quite interesting but there isn't much description of what currently works and what does not. | 19:37 |
| tpb | Title: Add 8/16/32 bit widths for block RAM inference · Issue #32 · SymbiFlow/yosys · GitHub (at github.com) | 19:37 |
| sf-slack2 | <tmichalak> @mithro: no, there is no reason for CLK_HROW_TOP_R.CLK_HROW_CK_IN_R0_ACTIVE going missing for kintex. Actually there are more bits missing, this is why I opened a ticket today (https://github.com/SymbiFlow/prjxray/issues/914) to investigate the root cause | 19:39 |
| tpb | Title: Investigate missing CLK_HROW PIPs bits for Kintex and Zynq · Issue #914 · SymbiFlow/prjxray · GitHub (at github.com) | 19:39 |
| hackerfoo | markus58: I started on it, but it turned out to be a bit more work that I thought: https://github.com/SymbiFlow/yosys/compare/master+wip...HackerFoo:infer_ramb36e1 | 19:41 |
| tpb | Title: Comparing SymbiFlow:master+wip...HackerFoo:infer_ramb36e1 · SymbiFlow/yosys · GitHub (at github.com) | 19:41 |
| sf-slack2 | <tmichalak> @mithro: there is no other fuzzer calculating those bits that is currently disabled, so I am kind of surprised that everything is there for Artix, but gone for Kintex or Zynq. I am pretty sure there is a small bug in the maketodo script | 19:41 |
| hackerfoo | markus58: Because brams_map.v will also need updated to map DI and DO correctly (no DIP/DOP for 8/16/32 bits): https://github.com/SymbiFlow/yosys/blob/master%2Bwip/techlibs/xilinx/brams_map.v#L164-L165 | 19:43 |
