Annotating multiple dmmmc sdf files with Xcelium

DaniK

Hi all,

After running STA multi-mode-multi-corners I get more than 20 sdf files. I would like to somehow check all of them without running manually more than 20 times xcelium.

Is there any way of doing this? I was thinking of writing a script that generates different argument files for xcelium. each one of them with a different conditional compilation for the testbench, something like this:

`ifdef SDF_ENABLE_1
initial begin
$sdf_annotate("M40_SSG_hold.sdf.gz",
tb.DUT,,"SSG.log","MAXIMUM");
end
`elsif SDF_ENABLE_2
initial begin
$sdf_annotate("M40_FFG_hold.sdf.gz",
tb.DUT,,"FFG.log","MINIMUM");
end
`elsif SDF_ENABLE_
// etc
`endif

Any other ideas? It is a very basic systemverilog testbench, I just want to check timing violations in the log files.

Thanks in advance,

  • Well, just in case someone comes to this post, I solved it this way.

    I wrote a little script that runs xcelium with the argument file:

    #!/bin/bash

# load xcelium
module add XCELIUM

# Generate directories
for i in {1..20}
do
  mkdir corner_$i
done

# Run xcelium in each directory
for i in {1..20}
do
  cd corner_$i
  xrun -f ../args -define SDF_ENABLE_$i &
  cd ..
done
