Circuit ** first line
Error on line 5 : vvsup vdd 0 pulse(psup 0 100u 0.1u 0.1u 1 2) DC=0
no such parameter on this device
ngspice stopped due to error, no simulation run!
ERROR: fatal error in ngspice, exit(1)
if I swap V1 and V2 of the pulse source such as
vvsup vdd 0 PULSE(0 psup 100u 0.1u 0.1u 1 2) DC=0
the simulation runs fine as expected, did anyone see that?

Thank you for this observation, I found it very helpful because I'm
working on such issues at the moment.
The actual (software) root cause is not the position of the parameter
in the list, but the absence of a space when not specifying the single
quotes. Either one of the following works:
According to the syntax shown in the manual, the order of sources is first DC, then AC, then DISTOF1, then DISTOF2, then one of the 9 independent source functions (PULSE, EXPONENTIAL .. external data). Putting DC at the end of the list is unusual. Currently it happens to work in at least some cases, e.g. here.

I'm trying a very simple circuit below

Please put single quotes around psup:
vvsup vdd 0 PULSE('psup' 0 100u 0.1u 0.1u 1 2) DC=0Holger

thanks for picking it up, when enclosed in quotes it works, when adding a leading space it also works
