Help:DC sweep using DAC

Question asked by smithc on Oct 1, 2006

Dear all:

I intend to do a DC sweep using DC source values specified by an DAC component pointing to a measured data file (first column of the datafile labeled as Vvf). Although I tried the "discrete" and "generic MDIF" format with the second line of the datafile content set to either "% Vvf(1) Iif(1)" or "%Vvf(real) Iif(real)" or simply "%Vvf Iif". The simulator always refused to work with the error " SRC1.Vdc mismatched argument type" popped up. Would you please give a hint what's gone wrong?

Thanks in advance for your help!

Best regards,


Notes(partial of the datafile):

BEGIN DSCRDATA    
%Vvf(real)    Iif(real)
1.80667    4.26E-04
1.83333    8.52E-04
1.8637    1.58E-03
.....
END DSCRDATA
