Accessing spectre simulation results in an ocean script

berbagci

Hi Andrew,

I have a very weird problem. I have checked other posts but couldn't figure it out. Hence, I decided to post here.

So I'm simulating a design in spectre simulator (an extracted netlist in spectre format). I have an ocean script and simulation runs without any problem. I want to do some calculations with the results.

However, I cannot seem to access any of the low level nets (although I can see them with outputs() command). 

For instance after typing outputs(), I get:

("/C/N_XC11/XLC/TCONF<128>_XC11/XLC/XBLE<2>/XLUT/XLUT_L1<0>/XI0<0>/MM2<0>_g" "/C/N_XC11/XLC/TCONFB<128>_XC11/XLC/XBLE<2>/XLUT/XLUT_L1<0>/XI0<0>/MM13<0>_g" "/C/N_XC11/XLC/TCONF<130>_XC11/XLC/XBLE<2>/XLUT/XLUT_L1<0>/XI0<0>/MM2<2>_g" "/C/N_XC11/XLC/TCONFB<130>_XC11/XLC/XBLE<2>/XLUT/XLUT_L1<0>/XI0<0>/MM13<2>_g" "/C/N_XC11/XLC/VSS_FIRE<5>_XC11/XLC/XBLE<2>/XLUT/XOTP<2>/XPUF_CELL/MHCI_TR_s" "/C/N_VSS_XCH_DUMMY/X33/XI8/XI203/MM5_s"

)

As seen here, I'm trying to access some low level nets. 

when I try getData("/C/N_VSS_XCH_DUMMY/X33/XI8/XI203/MM5_s"), it returns nil. Also tried to access nets that were part of an array (<>) by using "\", that didn't work either.

I tried getData("C.N_VSS_XCH_DUMMY.X33.XI8.XI203.MM5_s"), again getting nil. For some reason I cannot access any of the available nets. I checked runObjFile, directories (netlist>map, amap, psf etc.). Everything seems to be ok. I will be glad if you can help me out. 

Any help greatly appreciated. Thanks

    Burak,

    What LVS and Extraction tool are you using? I suspect the slashes in the netlist/simulator names are confusing the name mapping, but the naming convention does sound a bit unusual, so I suspect something is not following normal naming conventions.

    Andrew.
