Device variation has
been a long-standing problem in custom design. Over the years, our customers
have made many attempts to model the behavior though parameterization, simulation
model extensions, sub-circuits, and by just "guessing" as to what might happen.
As the mathematical complexity of each node increases, so does the difficulty
of making sure all the design possibilities are covered during the initial
design phases. That's where the Virtuoso Analog Design Environment GXL can
Created to use all of
the tests and measurements developed inside Virtuoso Analog Design Environment XL,
the GXL tool can help you during four distinct design phases:
by helping the engineer retarget existing IP to new processes
In-design by providing a host of sophisticated tools for developing worst case corners,
yield improvement mini-flows using matching, tuning, and optimization, and
high-yield analysis for discovering circuit behavior at 6-sigma.
During physical implementation by allowing the designer to take "snapshots" of
the partial layout to see how parasitics from routing or placement could be
skewing the desired results before the design is completed and locked down.
Post-extraction, verifying the design is still meeting specification even after
the full hierarchical physical implementation is completed
With Cadence's unique
token licensing within the Virtuoso Analog Design Environment GXL platform,
licenses never sit idle since the tokens are flexible enough to cover all of the
technology or be used to run ADE XL/L cockpits when not needed for variation design.
That makes the adoption of Virtuoso Analog Design GXL easy technically and easy
on the budget. Over the next seven weeks, our technical experts here at
Cadence will be showcasing six major capabilities contained
within the tool:
Creating and using worst case corners
Fast yield analysis and statistical corners
Mismatch variance contribution and yield contribution
Design migration and retargeting
Circuit tuning and optimization
High yield analysis and optimization
