can u suggest in the definitation of resistor what does mult specify. w and l are width and length perhaps. -------------.subckt sky130_fd_pr__res_high_po_0p35 r0 r1 b + .param w = 0.350 l = 5 mult = 1.0

search slack for "mult" this is a known issue

@Manoj Sharma 'mult' specifies how many parallel devices you are using. However the multiplier in spice is called 'm' so the correct syntax for using more parallel resistors (like any subcircuit) is to use: XRxxx node1 node2 substrate_node model w=.. L=.. mult=<n> m=<n>, where <n>=integer number. The reason for using mult is that statistical mismatch parameters depend on total size ( W * L * m) however since 'm' is not accessible from inside the model another 'mult' parameter is used.
