[Help-gnucap] 555 subcircuit

[éric boucharé]

Hello,

I have tried gnucap since last week for different little things. It runs
quite nice. Viewing results with gwave is nice as well.

A question : I have tried to simulate a 555 circuit using a subcircuit
provided on the TI web site. Here it is

555 astable circuit
RL 4 0 100k 
Valim 5 0 dc 10
X1 0 2 4 5 3 2 1 5 TLC555 
C2 0 3 10nF IC=0 
C1 0 2 100nF IC=0 
RA 1 5 4.7k 
RB 2 1 5.6k

Running it with gnucap 0.33 in batch mode gives the following :

MOSMOD: rd input, but not rs. setting rs = 0.
M1.X1: model type mismatch: MOSMOD

And then it ends.Can someone tell me what's wrong ?

Thanks
