Static power analysis with SOC

...

 Hi David,

I assume you mean a power consumption report (command reportPower). If you are using MMMC, then you should have a view set up with BC .libs and rc_corner of CWORST. Then you can just set that as the active view and run reportPower with the options of your choosing. If you're not using MMMC, then the design should be loaded with the BC .libs and you should have run an RC extraction with a CWORST QRC tech file or FE captable. I'm not sure if this completely answers your question.

 Hi Kari,

Thanks for the reply.

Which Cadence tools is the most appropritated to generate this report ?

David.

Hi Kari,

Please take a look at this Encounter power report script :

=============================================

loadConfig design.conf
defIn design.def

# use Min lib + BCCOM OPC for power corner
setTimingLibrary -max Min -min Min

# use CWORST RC corner
defineRCCorner -late {worst} 125 -early {worst} 125
setExtractRCMode -engine detail

extractRC

reportPower -outfile power.rep -sort { total }

======================================

config file :

======================================

global rda_Input
set rda_Input(ui_netlist) "design.v"
set rda_Input(ui_topcell) { top }

# LEF Files
set rda_Input(ui_leffile) "tcbn45gsbwp_7lm4X2ZRDL.lef"

# WORST LIB
set rda_Input(ui_timelib,max) "tcbn45gsbwpwc.lib"

set rda_Input(ui_timelib,min) "tcbn45gsbwpbc.lib"

set rda_Input(ui_timingcon_file) "design.sdc"

set rda_Input(ui_captbl_file) " \
-typical cln45gs_1p07m+alrdl_typical_top2.captable \
-best cln45gs_1p07m+alrdl_cbest_top2.captable \
-worst cln45gs_1p07m+alrdl_cworst_top2.captable"

======================================

Can you please review this code and let me know if it is OK.

David.

 David,

The command reportPower is used inside SoC-Encounter. You could also run the tool powermeter. In fact, reportPower runs powermeter "under the hood". Running powermeter standalone involves more setup on your part, but also more flexibility if you have a complicated design.

 I think your script looks ok - you are missing the pwr/gnd info from the .conf file though. You may want to add some lines like the following:

set rda_Input(ui_pwrnet) {VDD}
set rda_Input(ui_gndnet) {SS}
set rda_Input(PIN:VDD:) {VDD}
set rda_Input(PIN:VSS:) {VSS}
set rda_Input(TIEHI::) {VDD}
set rda_Input(TIELO::) {VSS}
