Hello Team,
We are trying to run a simulation by downloading a SPICE model from SN74LVC16244A product page in TI.COM and importing it into OrCAD PSPICE, but we see an error and it does not work it. The error shown " values must be monotonic creating ".
Is there a way to resolve anything?
Best regards,
Sato
Hello Sato-san,
This issue is caused by a lookup table that includes two values for the same input. Some simulators handle this without errors while others have an issue with it.
You can use any text editor to modify the file, remove one of the lines from each table and change the values as shown below:
I have included the updated code below to make the conversion easier.
EROH NROH VEE TABLE {V(VCC,VEE)} =
+(1.65,112.5)
+(2.3,50)
+(3,33.333)
+(4.5,21.875)
EROL NROL VEE TABLE {V(VCC,VEE)} =
+(1.65,112.5)
+(2.3,37.5)
+(3,23.958)
+(4.5,17.1875)
Please let me know if I can be of further assistance.
