Hi everyone,
I am now doing P&R in Encounter and would like to add QRC extraction into this flow. I checked the Encounter flow and used the following command to do this job.
setQRCTechfile qrcTechFile
setExtractRCMode -engine postRoute -effortLevel medium -incremental true
optDesign -postRoute
optDesign -postRoute -hold
The qrcTechFile is read in before the postRoute optimization operation. However, when Encounter carried out these commands, it reported the following error and then terminated automatically.
**ERROR: (ENCEXT-1206): Message by Extraction engine during initialization: Error [input]: Layer RX: Error in R-equation: can't read "w_g": no such
variable.
R-equations must have Tcl syntax, 8 input parameters (p_c, w_n, sn_gn,
d_gb, d_gc, et_cd, eb_cd and w_d) and 2 output parameters (R_eq_status and
R_eq_value).
Check R-equation description in the ICT file. . Log file is 'extLogDir/TQRC_11-Jul-2015_22:17:58/extr.SeqDet.0.extraction_engine.log'
Encounter terminated by internal (SEGV) error/signal...
I am not sure why this occurred. Is there anything incorrect in my script?
Thanks for any suggestions.
