problem with post synthesis simulation with Scirocco using s

Thu Apr 06, 2006 4:46 pm   

Hi All,
I have a vhdl file compiled by the Design Compiler. I also wrote out an
sdf file from DC. Now to do the post synthesis simulation, I am using
scirocco. When it is invoked with the following command

../scsim -sdf /TB_ADDER/UUT/:adder.sdf

it gives errors saying that it cannot find instances S_0, S_1 and so
on.. but they are very much present in the SDF file.

This is how the sdf file looks like:

(DELAYFILE
(SDFVERSION "OVI 2.1")
(DESIGN "adder")
(DATE "Wed Apr 5 16:38:17 2006")
(VENDOR "osu025_stdcells")
(PROGRAM "Synopsys Design Compiler cmos")
(VERSION "X-2005.09-SP3")
(DIVIDER /)
(VOLTAGE 2.50:2.50:2.50)
(PROCESS "typical")
(TEMPERATURE 25.00:25.00:25.00)
(TIMESCALE 1ns)
(CELL
(CELLTYPE "adder")
(INSTANCE)
(DELAY

(INTERCONNECT b S_0/B (0.000:0.000:0.000))

(INTERCONNECT cin S_1/B (0.000:0.000:0.000))
(INTERCONNECT a S_2/A (0.000:0.000:0.000))

(INTERCONNECT S_2/Y S_4/B (0.000:0.000:0.000))
)
)
)
(CELL
(CELLTYPE "XOR2X1")
(INSTANCE S_0)
(DELAY
(ABSOLUTE
(IOPATH A Y (0.179:0.179:0.179) (0.140:0.140:0.140))
(IOPATH B Y (0.197:0.197:0.197) (0.160:0.160:0.160))
)
)
)
(CELL
(CELLTYPE "AND2X1")
(INSTANCE S_1)
(DELAY
(ABSOLUTE
(IOPATH A Y (0.109:0.109:0.109) (0.138:0.139:0.139))
(IOPATH B Y (0.104:0.104:0.104) (0.115:0.115:0.115))
)
)
)

I would really appreciate if someone could please help me solve this
problem.

Thanks,
Fazela

I will meet the same problem in my post simulation, I hope some
engineers gan help me sloving this problem.
