    sdf generated by Astro and PT,any difference?

    Before physical design the sdf file generated by PT will include the interconnect dellays (which are modelled) for the timing verification spef file generated by Astro will contain the exact delay information about the delay

    convolution and correlation

    convolution: when we know the impulse response of LTI system, by convolving the input with the impulse response of the system we can find the response of the system for that input (similarly you can find the response for any input with the convolution). correlation: this is the mathematical...

    What are the details about level shifter and isolation cells

    Re: multi voltage flow Check out low power design guide
  20. H

    Why the isolation cells are required in a low power multivoltage design?

    Re: Isolation cells When you power down a domain, the charges get accumulated in the intermediate nodes (floating nodes ). If this intermediate node is input to the always on block will cause short ciruit current.
