Re: [Help-gnucap] Help: error using parameters in a subcircuit

Hello again, i made a mistake

here is the error is V vin 0 pulse  0 1.5 1m 1m 1m

actually I have created parameters for voltage-controlled
voltage source gains and change the quotes by braces but
the problem persists ...

here is the new netlist

*test
.subckt tx (a1 a2 b1 b2 c1 c2)
.param M12={K12 * sqrt (L1 * L2)}
.param M23={K23 * sqrt (L2 * L3)}
.param M13={K13 * sqrt (L1 * L3)}
.param G12={M12/L1}
.param G21={M12/L2}
.param G13={M13/L1}
.param G31={M13/L3}
.param G23={M23/L2}
.param G32={M23/L3}
l1 (a3 a2) {L1}
l2 (b3 b2) {L2}
l3 (c3 c2) {L3}

e21 (a4 a3 b3 b2) {G21}
e31 (a1 a4 c3 c2) {G31}
e12 (b4 b3 a3 a2) {G12}
e32 (b1 b4 c3 c2) {G32}
e13 (c4 c3 a3 a2) {G13}
e23 (c1 c4 b3 b2) {G23}
.ends
