I would like to add the resistor with the following hspice code into my library in Cadence. Is there any good way to add it?

.subckt rlrrf plus minus psub w=2e-6 l=10e-6 strips=1
.param cterm = 0.1013e-3
.param lterm = 0.84e-6
.param rterm = 29.39
.param width = w
.param ns = strips
.param length = 'l/ns'
.param dw = 0.25e-06
.param rhoply = 72.0
.param coxp = '0.1013e-3*coxpf'
.param tc_S1 = 18.0e-04
.param res = 'ns*((rhoply*length)/(width-dw)+rterm*1e-6/(width-dw))'
.param cfox = 'ns*(coxp*(length)*(width-dw))'
.param ccnt = 'ns*cterm*lterm*(width-dw)'
r1 plus 1 'res/2' tc1=tc_S1
r2 1 minus 'res/2' tc1=tc_S1
c1 plus psub 'ccnt'
c2 1 psub 'cfox'
c3 minus psub 'ccnt'
.ends rlrrf

Thank you very much for your time,

You can add to model file. And the wirte form just like the model file resistor form.
Then you can use analog resistor. Just needs to wirte the correct model name.
