Hi,
I'm having a problem with another program that use LTSpice to run the simulation. The schematic have a NAND gate, and I write a ".model" like the one below, but the LTSpice seems don't recognize the "d_nand" expression.
** 2 input NAND schmitt
.model A4093 d_nand ( in_family="4000-5_SCHMITT"
+ out_family="4000-5"
+ out_res=560
+ input_load=5p
+ rise_delay=162n
+ fall_delay=162n
+ max_source = 3.2m
+ min_sink = -1m )
Anyone know how can I solve this?
Best regards,
S.
Hello S,
The reason LTspice doesn't recognise your NAND gate is because it isn't a native model. This model is from another flavour of SPICE, and won't work at all. LTspice does not support logic elements from other simulators unless they are transistor level models.
I recommend you use a native A source device. Check the help file for the correct syntax.
Regards,
Tony
