Help with spectre stimulus file for sram read.

rajrevanth61

Hello Experts,

 I have a spectre stimulus file for SRAM read operation , but when i include the file and simulate via the spectre, I am not getting the expected results, can anyone check if my stimulus file is correct or not.

simulator lang=spectre
global gnd!
vdd (vdd! 0) vsource dc=1
gnd (gnd! 0) vsource dc=0
ic Q=1 Qb=0 BL=1 BLB=1
v6 (WL 0) vsource type=pwl wave=[0 0 20n 0 22n 1 40n 1v 42n 0v]

 Please help me.

Thanks

    Hello,

    When I try to simulate the above circuit using the initial conditions(ADE->Simulation->Convergence Aids->Initial Condition) and sources directly in the circuit. i am getting the output correctly.

    But i when i try to simulate it through the stimulus file, I am not getting the required output.
    Is this stimulus file correct?
    simulator lang=spectre
    global gnd!
    vdd (vdd! 0) vsource dc=1
    gnd (gnd! 0) vsource dc=0
    ic Q=1 Qb=0 BL=1 BLB=1
    v6 (WL 0) vsource type=pwl wave=[0 0 20n 0 22n 1 40n 1v 42n 0v]
