| + | |||
| + | ===== Subcircuit with parameters ===== | ||
| + | |||
| + | Some simulators (LTspice, Pspice) accept a syntax for subcircuits that is incompatible with gnucap. | ||
| + | |||
| + | ==== Subcircuit instantiation syntax ==== | ||
| + | |||
| + | LTspice syntax: | ||
| + | |||
| + | Xv v1r v1i vri_slack params: ( vr=10 vi=1 on=1 vfactor=1.732 ) | ||
| + | Ximp v1r v1i 0 0 impedance params: ( r=1 xl=10 xc=2 length=1 zfactor=1 ) | ||
| + | |||
| + | The key ''params:'' should be omitted.\\ | ||
| + | Gnucap syntax: | ||
| + | |||
| + | Xv v1r v1i vri_slack ( vr=10 vi=1 on=1 vfactor=1.732 ) | ||
| + | Ximp v1r v1i 0 0 impedance ( r=1 xl=10 xc=2 length=1 zfactor=1 ) | ||
| + | |||
| + | ==== Subcircuit declaration syntax ==== | ||
| + | |||
| + | LTspice syntax: | ||
| + | |||
| + | .subckt impedance v1r v1i v2r v2i | ||
| + | + params: | ||
| + | + on = 1 | ||
| + | + r = 100 | ||
| + | + xl = 0 | ||
| + | |||
| + | .subckt impedance v1r v1i v2r v2i params: on = 1 r = 100 xl = 0 | ||
| + | |||
| + | The list of parameters is not accepted on the header line. Instead, list the parameters with .param statements on following lines.\\ | ||
| + | Gnucap syntax: | ||
| + | |||
| + | .subckt impedance v1r v1i v2r v2i | ||
| + | .param | ||
| + | + on = 1 | ||
| + | + r = 100 | ||
| + | + xl = 0 | ||
| + | |||
| + | .subckt impedance v1r v1i v2r v2i | ||
| + | .param on = 1 r = 100 xl = 0 | ||
