Syntax of Vbit source used in spectre simulator in hspice (.sp file)

rtyuy

Hi , i am using spectre simulator in the cadence virtuoso. i want to  use the generated netlist of my schematic in synopsis  hspice. i am giving input to  one of the node through vbit say  (10101101010101000011010010010101010).  since i don't have  hspice D simulator, can anyone please help with syntax of vbit in .sp file??

here is syntax in spectre simulator

V0 (IN gnd) vsource type=bit val0=0 val1=1.2 period=3n data="0000111111111111111111111111111111111100000000000000001111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111" rptstart=1 rpttimes=0

  • Probably better to ask Synopsys, but I think it's something like this:

    V0 IN and     PAT 1.2 0 0.0 10e-12 10e-12 3e-9 b0000111111111111111111111111111111111100000000000000001111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111 RB=1 R=0

    I set the rise and fall times to be 10ps in this case.
