You're going to have to provide more information.  For example: what kind of adc?  I'm not sure your question even makes sense for a sigma-delta converter.

Satya,

 Assuming you have access to Virtuoso, IC61x, in the ahdlLib are
example components to measure INL and DNL of a data converter.
The examples are for 8 bit data converters, you will need to change
the variables for your designs and update the pins.

  I am perplexed by your request for a delay measurement. While
delay can be measured for data converter, performance is usually
unrelated to data converter delay. You might find it more useful to
perform a parametric sweep of the clock frequency and measure
the data converter parameters: THD, SFDR, SNDR, ... and decide
based on the performance across frequency what the maximum
performance is. All these functions are available in the IC615
version of ViVA when using the spectrum function.
