Question

I was able to WA the overlapp issue by tweaking the utilization now is in detailed routing however it doesn t seem to blow much steam I think openroad was using multiple cores in this step can it be enabled Currently using only 10 of CPU

Ahá there is a threads parameter that needs to be passed to TritonRoute params ``` lef objects sw130 copperv merged spacing lef def results sw130 copperv 4 cts def guide results sw130 copperv route guide output results sw130 copperv 5 route def outputTA objects sw130 copperv 5 route TA def outputguide results sw130 copperv output guide mod outputDRC reports sw130 copperv 5 route drc rpt outputMaze results sw130 copperv maze log threads 16 cpxthreads 1 verbose 1 gap 0 timeout 2400```

Hmm Did it actually use 16 threads with that parameters file i e if you check with `top` or similar Last time we tired it threading wasn t yet implemented but that was long ago

Yes top and the laptop FAN are in agreement ```PID COMMAND CPU TIME TH WQ PORTS MEM PURG CMPRS PGRP PPID STATE BOOSTS CPU ME CPU OTHRS UID FAULTS COW MSGSENT MSGRECV 53016 TritonRoute 546 3 49 33 36 16 16 0 41 283M 0B 0B 52845 52845 running 0 1 0 00000 0 00000 501 4200989+ 99 281 90```

Btw I don t know what that cpxthreads is about do you

It doesn t seem to be a valid parameter From the source code here are the valid ones ``` if field == lef LEF FILE = value ++readParamCnt else if field == def DEF FILE = value REF OUT FILE = DEF FILE ++readParamCnt else if field == guide GUIDE FILE = value ++readParamCnt else if field == outputTA OUTTA FILE = value ++readParamCnt else if field == output OUT FILE = value ++readParamCnt else if field == outputguide OUTGUIDE FILE = value ++readParamCnt else if field == outputMaze OUT MAZE FILE = value ++readParamCnt else if field == outputDRC DRC RPT FILE = value ++readParamCnt else if field == threads MAX THREADS = atoi value c str ++readParamCnt else if field == verbose VERBOSE = atoi value c str else if field == dbProcessNode DBPROCESSNODE = value ++readParamCnt else if field == drouteOnGridOnlyPrefWireBottomLayerNum ONGRIDONLY WIRE PREF BOTTOMLAYERNUM = atoi value c str ++readParamCnt else if field == drouteOnGridOnlyPrefWireTopLayerNum ONGRIDONLY WIRE PREF TOPLAYERNUM = atoi value c str ++readParamCnt else if field == drouteOnGridOnlyNonPrefWireBottomLayerNum ONGRIDONLY WIRE NONPREF BOTTOMLAYERNUM = atoi value c str ++readParamCnt else if field == drouteOnGridOnlyNonPrefWireTopLayerNum ONGRIDONLY WIRE NONPREF TOPLAYERNUM = atoi value c str ++readParamCnt else if field == drouteOnGridOnlyViaBottomLayerNum ONGRIDONLY VIA BOTTOMLAYERNUM = atoi value c str ++readParamCnt else if field == drouteOnGridOnlyViaTopLayerNum ONGRIDONLY VIA TOPLAYERNUM = atoi value c str ++readParamCnt else if field == drouteViaInPinBottomLayerNum VIAINPIN BOTTOMLAYERNUM = atoi value c str ++readParamCnt else if field == drouteViaInPinTopLayerNum VIAINPIN TOPLAYERNUM = atoi value c str ++readParamCnt else if field == drouteEndIterNum END ITERATION = atoi value c str ++readParamCnt else if field == OR SEED OR SEED = atoi value c str ++readParamCnt else if field == OR K OR K = atof value c str ++readParamCnt ```
