lekernelwow, vivado takes 2min 18s just to *parse* the lm32 source code12:17
Fallenoumaybe afterward place and route is much more efficient ? :)12:24
lekernelwow no, everything is mega slow12:32
lekerneleven opening the netlist to automatically create clock constraints in the GUI takes minutes12:32
Fallenouweird :/12:33
Fallenoueven the old ISE was not like that12:33
lekernelthe power of java: combining the development slowness of compiled languages with the runtime slowness of interpreted languages12:35
lekernelaha! seems lm32 can run at 200MHz in kintex 712:59
kristianpaulcould* ?13:14
kristianpaulor you actually got it runnungin?13:14
kristianpauleven 150mhz the worst case, is a nice jump :)13:15
lekernelaccording to vivado p&r results, it can13:18
lekernelactually, among those 2-3min  most14:23
lekernelare spent loading the libraries14:23
Fallenounice techno improvement :)14:40
Fallenoumore than 2x speedup !14:41
Fallenoulekernel: is vivado using map, par, xst ? or new tools ?14:42
Fallenouis it just another gui?14:43
lekernelnew tools14:48
lekernelseems they rewrote the whole thing in java (lol)14:48
lekernelsynthesis + PAR of a 8-bit shift register (!) takes more than 30 minutes14:49
lekernelmost of it, of course, is spent doing autocrap-style tasks like loading libraries, checking licenses and other inane things, etc.14:49
Fallenoudear god14:55
FallenouI can build my minimalist mmu-enabled soc in 5 min with my new core i5 desktop computer :)14:55
Fallenouusing old tools on 14.114:56
cdelekernel: could you send me any .jar from vivado, for example from the P&R?18:07
lekernelphew, it's huge... gigabytes...18:11
lekernelprobably easier you download it yourself from xilinx18:11
lekernelwhat are you looking for exactly?18:12
