3.1i Vitex-E PAR - Router appears to hang on V2000E design early in the 2nd iteration.


Keywords: Route, Router, Hang, Hung, Slow, Runtime

Urgency: Standard

Problem Description: Cases have been seen where the Virtex-E router slowed
to the point of appearing to be hung during the 2nd router iteration. In
each case, the problem was due to timing constraints that were not possible
to meet. The router was trying too hard to meet the constraints rather than
quitting with a message explaining the situation.


A change will be made in the next major release after 3.1i so
that the router will quit earlier rather than trying to meet impossible
time specs.
