Correct and complete timing constraints
are key to a smooth chip-implementation flow. Missing constraints cause
wasted timing closure iterations. Incorrect constraints result in
silicon failure. Poorly written constraints increase runtime of
implementation tools. Either way, getting your constraints right is key
to efficient and safe chip implementation. Leading semiconductor firms
have recognized that the
automation of constraint generation, verification and management tasks
is a must in today's implementation flow.
FishTail is the leading provider of design automation tools targeted at
timing constraint generation, verification and management tasks. FishTail's focus is on providing a comprehensive and best-in-class
solution to any and all constraint related tasks performed as part of
chip implementation.
FishTail's products allow RTL designers to
generate clock constraints,
i/o
delays, clock groups and clock senses to ensure that design clocking is
accurately reflected in the design constraints. RTL designers can also
generate timing critical false and multi-cycle paths. From a
verification standpoint FishTail products allow RTL designers to
establish that they have correctly specified the clocks and case
analysis on a design and formally prove that their false and multi-cycle
paths are correct.
For back-end chip-implementation teams FishTail provides a solution for
the automatic merging of multi-mode design constraints so that P&R
runtimes are halved. FishTail promotes IP constraints to the full-chip
to facilitate design reuse in SoCs. FishTail
retargets constraints to
each new design representation generated as part of the implementation
flow. Finally, FishTail allows implementation teams to perform an
equivalence check of their post-layout constraints with their pre-layout
constraints to ensure that constraint integrity is maintained during the
implementation flow.
FishTail has three major products: Focus (for the generation of design
constraints), Confirm (for the verification of design constraints) and
Refocus (for the management of design constraints). With FishTail's
suite of products for constraint generation, verification and
management, design teams are empowered to implement better quality chips
with greater confidence in much less time! |
