Missing net and Cell Names-exporting gds2 from encounter , importing it in Caliber

asinghct
Hi, I am missing net as well as cell name information when I am exporting GDS2 from encounter and importing it into caliber (for RC+ coupling capacitance) extraction. Any suggestions on how to do it. Thanks Amit
  •  When you are exporting GDS2 in encounter, there are options to attach instance and net names. I hope this helps.

     streamOut
        gdsFile
        [-attachInstanceName attributeNumber]
        [-attachNetName attributeNumber]
  • Thanks for your reply, actually I tried it, but not working, maybe I am making mistakes about attribute number which I am giving as some random number between 0-127, (different numbers for Instance Name and Net Name Thanks Amit

  • If you can post some of your error or warning when you  try to run Calibre extraction using GDS2 from encounter, that will make your problem more clear.

    Are you getting something " ERROR: Cell MX2X2 is referenced but not defined." when importing GDS2 in calibre?

     

  •  In your Encounter streamOut map file, do you have a NAME section? Refer to the documentation for the streamOut command, under the -mapFile option.

  • Hi, yes I am getting this message in Caliber. Pls find enclosed my map file for encounter and Caliber errors that I am getting. I tried adding the name in the map files and its not working ..... ------------------------------------------------------------------------------------------------------- ENCOUNTER MAP FILE ------------------------------------------------------------------------------------------------------- metal1 NET 49 0 metal1 SPNET 49 0 metal1 PIN 49 0 metal1 FILL 49 0 metal1 VIA 49 0 metal1 VIAFILL 49 0 NAME metal1/PIN 49 0 NAME metal1/SPNET 49 0 metal2 NET 51 0 metal2 SPNET 51 0 metal2 PIN 51 0 metal2 FILL 51 0 metal2 VIA 51 0 metal2 VIAFILL 51 0 NAME metal2/PIN 51 0 NAME metal2/SPNET 51 0 metal3 NET 62 0 metal3 SPNET 62 0 metal3 PIN 62 0 metal3 FILL 62 0 metal3 VIA 62 0 metal3 VIAFILL 62 0 NAME metal3/PIN 62 0 NAME metal3/SPNET 62 0 metal4 NET 31 0 metal4 SPNET 31 0 metal4 PIN 31 0 metal4 FILL 31 0 metal4 VIA 31 0 metal4 VIAFILL 31 0 NAME metal4/PIN 31 0 NAME metal4/SPNET 31 0 metal5 NET 33 0 metal5 SPNET 33 0 metal5 PIN 33 0 metal5 FILL 33 0 metal5 VIA 33 0 metal5 VIAFILL 33 0 NAME metal5/PIN 33 0 NAME metal5/SPNET 33 0 metal6 NET 37 0 metal6 SPNET 37 0 metal6 PIN 37 0 metal6 FILL 37 0 metal6 VIA 37 0 metal6 VIAFILL 37 0 NAME metal6/PIN 37 0 NAME metal6/SPNET 37 0 metal7 NET 39 0 metal7 SPNET 39 0 metal7 PIN 39 0 metal7 FILL 39 0 metal7 VIA 39 0 metal7 VIAFILL 39 0 NAME metal4/PIN 39 0 NAME metal4/SPNET 39 0 metal8 NET 41 0 metal8 SPNET 41 0 metal8 PIN 41 0 metal8 FILL 41 0 metal8 VIA 41 0 metal8 VIAFILL 41 0 NAME metal5/PIN 41 0 NAME metal5/SPNET 41 0 metal9 NET 43 0 metal9 SPNET 43 0 metal9 PIN 43 0 metal9 FILL 43 0 metal9 VIA 43 0 metal9 VIAFILL 43 0 NAME metal6/PIN 43 0 NAME metal6/SPNET 43 0 metal10 NET 45 0 metal10 SPNET 45 0 metal10 PIN 45 0 metal10 FILL 45 0 metal10 VIA 45 0 metal10 VIAFILL 45 0 NAME metal6/PIN 45 0 NAME metal6/SPNET 45 0 via VIA 50 0 via VIAFILL 50 0 via2 VIA 61 0 via2 VIAFILL 61 0 via3 VIA 30 0 via3 VIAFILL 30 0 via4 VIA 32 0 via4 VIAFILL 32 0 via5 VIA 36 0 via5 VIAFILL 36 0 via6 VIA 38 0 via6 VIAFILL 38 0 via7 VIA 40 0 via7 VIAFILL 40 0 via8 VIA 42 0 via8 VIAFILL 42 0 via9 VIA 44 0 via9 VIAFILL 44 0 ----------------------------------------------------------------------------------------------------------------------------------- Caliber Error (snapshot)while trying to extract parasitics ------------------------------------------------------------------------------------------------------------------------------------- Error: No matching ".SUBCKT" statement for "SDFF_X1" at line 158 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "SDFF_X1" at line 160 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "MUX2_X1" at line 162 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "NOR2_X1" at line 163 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "MUX2_X1" at line 164 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "NOR2_X1" at line 165 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "INV_X1" at line 166 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "SDFF_X1" at line 167 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "SDFF_X1" at line 169 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "INV_X1" at line 171 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "SDFF_X1" at line 172 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Error: No matching ".SUBCKT" statement for "SDFF_X1" at line 174 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v.sp" Thanks Amit
  • Pls note that in the above copy/Paste of map file formatting is missing -there are line breaks after every 4 strings as desired in a mapfile. Thanks Amit

  •  I'm not a Calibre expert, but it looks like the verilog of your std cells was not included when you generated your netlist. Check your v2lvs settings.

  • Hi, Thanks for your reply.. Did that still getting following errors--for AND, OR, NOT these are used in the verilog library- tried writing a module of my own for AND, OR, NOT but-it was not accepted, not looked at DFF though Error: No matching ".SUBCKT" statement for "SDFF_X1" at line 174 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v_NangateOpenCellLibrary_typical_conditional.v.sp" Error: No matching ".SUBCKT" statement for "AND" at line 441 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v_NangateOpenCellLibrary_typical_conditional.v.sp" Error: No matching ".SUBCKT" statement for "OR" at line 442 in file "/home/akumar3/intr/benchmarks/iscas89/s298/s298/test/_Circuit298chains4.v_NangateOpenCellLibrary_typical_conditional.v.sp" Thanks Amit

  •  Can you post your v2lvs command with all the options you're setting?

  • Hi, Actually using gui, starting with run pex 1. In the inputs giving verilog as input -files my input verilog + library file 2. Adding hcell files 3. setting simulation type to gate level r+c+cc Thanks Amit
