lekernelseriously, swapping two completely regular synchronous signals between logic results in19:19
lekernelWARNING:Route:436 - The router has detected an unroutable situation for one or more connections. The router will finish the19:19
lekernelrest of the19:19
lekernel   design and leave them as unrouted. The cause of this behavior is either an issue with the placement or unroutable placement constraints.19:19
lekernel   To allow you to use FPGA editor to isolate the problems, the following is a list of (up to 10) such unroutable connections:19:19
lekernel         Unroutable      signal: m1crg/pllout4   pin:  m1crg/vga_clock_gen/CLKIN19:19
lekernelISE is such a pile of shit19:20

lekernelalright... let's unswap the signals, wait 15min, run the windu and motif based fpga editor bloatware, lock all suspicious components, swap the signals back, wait 15min, and try again ...19:24
lekernelah, I forgot the "instance not found" error cycles with a 5-minute wait before you can find what funny name Xst has made up for all of them19:25
lekernelyay, got color and only slightly buggy FPGA decoding!19:55

lekernelxdl is actually a bit less annoying to use than fpga editor for looking at instance placements21:03
lekernelxdl -ncd2xdl top-routed.ncd then grep for the instance you're looking for21:06

GitHub198milkymist-ng/master 11cbdf0 Sebastien Bourdeauducq: build.py: support single DVI sampler21:10
GitHub198milkymist-ng/master 784e96b Sebastien Bourdeauducq: build.py: LOC clock generator components to limit breakage of the ISE shitware21:10
Fallenou_a shame you need to lock components21:14
lekernelit doesn't even work!!! wtf21:15
lekernelit still gives me this "unroutable" bullshit when changing some constants (!) in the code...21:15
Fallenou_-_-21:15
lekernelwith the same signals, and the LOCed components at the locations that worked just before21:16
lekernelwell, I suppose multicore machines are for running multiple copies of the ISE shitware with different PRNG seeds, hoping that at least one will not display some stupid error message and will meet timing21:17
Fallenou_hum did you lock the PRNG seed ?21:19
Fallenou_ah you said that21:19
lekernelthe most expensive Vivado license is $5795, wow ;)21:20
lekernelI guess someone has to pay the tech support salaries ...21:20
Fallenou_;)21:22
