Hello all,
I am trying to use ibis_buffer found in the analogLib library by cadence.
i am connecting a differential resistance of 100 ohm between two
input pins defined by [Pin] of two different [Models] by using [Series Pin Mapping] keyword.
This is how i have added the series resistance:-
[Series Pin Mapping] pin_2 model_name function_table_group
1 2 R_term
3 4 R_term
[Model] R_term
Model_type Series
Polarity Non-Inverting
C_comp 0pF 0pF 0pF
[Temperature Range] 25 85 -40
[Voltage Range] 1.8 1.65 1.95
[R Series] 100ohm 90ohm 110ohm
This is passing the IBIS_parser but somehow the resistance between two [Pin]s is not getting detected.
Could somebody suggest me how to proceed?
I have two questions:-
1. Is ibis_buffer capable of identifying this series resistance?
2. Is there anything missing in the way I am inserting the series resistance?
Thanks,
Shreyas
