futarisIRCcloudmithro / rohitksingh: is one of the MAX3421E USB host shields that should  work. You can probably get it cheaper at other places though.03:45

futarisIRCcloudHey rohitksingh_work ...03:50
rohitksingh_workHi futarisIRCcloud!03:50
futarisIRCcloudCan you comment on Benno's ( @jeamland ) twitter post about USB Pmods?03:52
futarisIRCcloudrohitksingh_work: Can you comment on Benno's ( @jeamland ) twitter post about USB Pmods?03:52
rohitksingh_workfutarisIRCcloud: oh. replying to him just now03:56
mithrofutarisIRCcloud: that shield is way to complicated...03:58
rohitksingh_workwhich shield?04:02
futarisIRCcloudmithro: For USB? It should be pretty much plug and play. I did do a USB to FPGA thesis some 14 years ago. /

mithrofutarisIRCcloud: that is cheating04:04
futarisIRCcloudmithro: Yes, but for prototyping the rest of the system, it's enough. You're not going to get 480mbps bandwidth though. 12mbps or 1.5mbps only. And bandwidth limited by SPI.04:07
futarisIRCcloudmithro: / for USB over TCP/IP...04:07

mithrofutarisIRCcloud: you might just use a RPi Zero and Linux USB gadget04:09
futarisIRCcloudmithro: Yeah, that's the other alternative.  It'd work too, if we had TCP/IP over SPI slave...  With QSPI you'd probably get enough speed too.04:12
futarisIRCcloudmithro: - Last I checked no-one had written a TCP/IP over SPI.04:13

futarisIRCcloudmithro / rohitksingh_work : Yeah, the newer tinyfpga refactor / rewrite is much better. I wonder if a litex usb-serial bridge ripped from that would be useful.04:54

rohitksingh_workmithro / futarisIRCcloud: oh okay, then I need to go through the refactored version again04:58

gsmalikHi everyone. Has anyone here worked with Verilator? I am writing my gsoc proposal and was thinking of using verilator for unit testing of RTL. tldr: about verilator : It is a C++ based verilog simulator that is around 100 times faster than traditional RTL based simulators22:21

gsmalik Hi. I have been spending time on learning about webm technology. The webm project provides RTL deliverables to "semiconductor companies with firm plans to ship VP9 related products" for free. Do you think we can get one? Also, would the integration of this in our system be an exciting enough gsoc project?23:18
