I'm trying to simulate an RGB LED fader using a NE555 and CD4029 running on 9V. I've got the NE555 working in the simulation in astable mode. The problem is getting the CD4029B model to work.

I've loaded the CD4000.lib file into the lib\sub folder
Ive included the Spice directive .include lib\sub\cd4000.lib
I've set value to CD4029B which is a .SUBCKT in the CD4000.lib file.

The following warnings come up.

WARNING: Can't resolve .param vdd1=vdd
WARNING: Can't resolve .param speed1=speed
WARNING: Can't resolve .param tripdt1=tripdt

There are no .param settings for vdd, speed or tripdt set in the file. Are these values found in the manufacturer's documentation?

Any help would be much appreciated.

Cheers

 

Try set this

SpecLine VDD=9 SPEED=1 TRIPDT=5e-9

 

I've set value to CD4029B

You shouldn't need to set that value. The symbol already has a value. Just right-click on the symbol and edit the Vdd value to 9V.

 

Try set this

SpecLine VDD=9 SPEED=1 TRIPDT=5e-9

Thanks! I also had to get the pin assignments in the right order as well
