Presentations for the Dec. 4 and Dec. 11 meetings available...Hi IBIS Experts,
When I am trying to simulate IBIS_AMI_RX model with IBIS_AMI_test.exe from
Sisoft,
IBIS_AMI_test simulator break down.
This is my run_eq_noeq.bat which I only chage the IBIS_AMI_tx.dll to
IBIS_AMI_rx.dll
in order to call AMI RX model from candence.
Here I don't care about data validity, but want to check AMI model
inter-operability.
**********************************************************************
call cleanup.bat
cls
type ..\version.txt
copy tx_impulse_no_eq.csv tx_impulse.csv
IBIS_AMI_prbs.exe -f tx_impulse.csv | ^
IBIS_AMI_test.exe -f IBIS_AMI_rx.dll -i tx_impulse.csv -g -c >
waveform_rx_pad.csv
rename tx_impulse_out.csv impulse_rx_pad.csv
**********************************************************************
I checked and debugged the IBIS_AMI_rx.c source file, and finally found that
the problem is
from that AMI_INIT function in IBIS_AMI_RX didn't return any pointer,
AMI_parameters_out.
After I gave some value to AMI_parameters_out and recompiled it, everything is
ok.
**********************************************************************
*AMI_dll_memory_handle = ctf;
*AMI_dll_parameters_out = AMI_dll_parameters_in; // <<<add this statement
printf(" AMI_INIT FINISHED\n");
return 1;
**********************************************************************
I browse the IBIS BIRD104.1 and AMI_parameters_out is required and no optional.
Even with that AMI_parameters_out is required in IBIS BIRD, such parameter may
be ommited by
modeler carelessly. I think IBIS AMI model may also have the model quality
problem.
Then under such condition, how to avoid simulator break down is an issue for
EDA vendors.
If I made some mistake here, please kindly correct me.
Thanks and Happy New Year to Everyone!
