Input File to set Input Voltages

StreamCX

How can I set input voltages by using file in Cadence6?

Or how write code for this file?

Where 

¨1¨=5V, B0-Bx... is inputs.

    You may have to change the format a little, but essentially you'd use the Setup->Simulation Files and then set up a vector file.

    Some info is provided with "spectre -h vector" but the best place to find details is in Chapter 13 ("Digital Vector File Format") of the UltraSim User Guide at <MMSIMinstDir>/doc/UltraSim_User/UltraSim_User.pdf

    Regards,

    I add vector assigned to one pin.

    But analog signal from other sources, like vpwl,  vsource becomes  ¨1¨ (5V) or  ¨0"(-6V) only in time position, where I write that.

    For example, that was 0n 0;  4999n 0; 5000n 1. It is noemal.

    I want all Voltages before 5000n to equal 0 because I set them in vpwl. 

    But when I add vector described in file and assigned to indipendent pin , voltages not crossed with that pin becomes like 0n 0; 1000n .02 ; 2000n 0.3 ; 3000n 0.4; 5000n 1 ; 5100n 0.8;

    How can I fix it? 

    Another question: how can I set voltage to another pin B29? I need set voltages to many pins.
