Understanding correlation issues in design flows is critical if closure is to be achieved without extensive & time-consuming ECOs – between synthesis and implementation tools, between various steps of implementation, and between implementation and signoff. Typically, this is done in a detailed manner for a handful of paths (for example, the 10 most critical), and then globally using a simple metric to produce a scatter plot.

TimeVision provides an integrated solution for timing correlation, and more critically for debugging and understanding the source of correlation issues.
