02:31 <mithro> hackerfoo: Yes

02:32 <hackerfoo> But at least the documentation seems to be APL2, so it might be worth copying some of it.

21:00 <sf-slack2> <butta> I'm starting to look into fasm2bels. Running the top_bit.v tests are failing for me. Is this a known issue?

21:02 <litghost> butta: Be more specific?

21:04 <sf-slack2> <butta> I'm running make file_xc7_tests_buttons_buttons_basys3_artix7-xc7a50t-basys3-roi-virt-xc7a50t-basys3-test_top_bit.v in build/xc7/tests/buttons and get this traceback:

21:30 <litghost> butta: That error indicates a sink without a source

21:30 <litghost> butta: e.g. a top-level output without a connection

21:30 <litghost> butta: Which git commit are you at?

21:33 <sf-slack2> <butta> I'm at the most recent commit on master

21:33 <sf-slack2> <butta> a71a4f25922d9aac76103412a6fa4b1e2c883437

21:34 <sf-slack2> <butta> This is also in a completely unmodified directory. Just cloned master and built.

21:35 <litghost> butta: Okay, ya https://github.com/SymbiFlow/symbiflow-arch-defs/blob/master/xc7/tests/buttons/buttons_basys3.v is not fasm2bels compable

21:35 <tpb> Title: symbiflow-arch-defs/buttons_basys3.v at master · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com)

21:36 <litghost> butta: Why do you want fasm2bels on this particular design?

21:36 <litghost> butta: Anyways, because of the ROI, in order to be fasm2bels compatible all top level pins need to be used

21:36 <sf-slack2> <butta> We just randomly picked one that seemed to have a simple design

21:37 <sf-slack2> <butta> Don't need that one in particular, just trying to understand fasm2bels

21:37 <litghost> butta: buttons is missing tx, rx, and clk

21:37 <sf-slack2> <butta> Do all the other tests work with fasm2bels?

21:37 <litghost> butta: Everything under https://github.com/SymbiFlow/symbiflow-arch-defs/tree/master/xc7/tests/ff_sr_ce works

21:37 <tpb> Title: symbiflow-arch-defs/xc7/tests/ff_sr_ce at master · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com)

21:37 <litghost> butta: So do murax and scalable_proc

21:38 <litghost> butta: https://github.com/SymbiFlow/symbiflow-arch-defs/blob/master/xc7/tests/dram_test/dram_test_64x1d.v works too

21:45 <sf-slack2> <butta> @litghost Running ff_sr_ce now, thanks
