How to drive many pins using a single driver?

 Hello All,

Assuming there are 10 input pins in a schematic view need to be set at either 0 or vdd. Is there any way to set them using a signle vdc?, or 10 independent dc supplies are necessary for such a test?

 

Thanks,

A

    Hi,

    I may be missing something here, but it seems to me that you would use one source to supply a voltage to net "vdd" (say 5 volts), and then you connect net vdd to the inputs that need to be driven to that voltage.  For the inputs that need to be connected to 0v, these would probably connect to the "gnd" net (where I'm assuming the other terminal of the vdd supply is connected to).

    If you are simulating in ADE there is the capability of using a stimulus file where you can set up the stimulus in a graphical (or textual, I believe) way, driving the schematic pins directly without needing a test bench.

    I hope this helps, but if not, please clarify your requirements.

    Regards,

    Lawrence.
