Deterministic CMOS analog synthesis for semiconductor teams balancing circuit complexity, senior engineering capacity, and operating cost.
While digital flows rely on synthesis engines and automated place-and-route, analog blocks still consume weeks of manual transistor tuning and costly simulation queues.
Manual transistor sizing forces brute-force SPICE sweeps across hundreds of PVT corners. This exhausts expensive simulator license tokens (Spectre, HSPICE) and ties up server cluster compute for weeks without convergence guarantees.
Senior analog designers cost €150k–€250k/year in loaded compensation. Yet design teams lose up to 60% of an architect's billable quarter waiting on simulation queues and mechanically tweaking channel dimensions.
Migrating proven analog circuits between foundries or from planar CMOS to advanced nodes (28nm, FinFET) historically requires starting sizing from scratch—duplicating original NRE investment and delaying customer revenues.
A successful EDA platform must respect the engineer's need for physical rigor while providing executive leadership with predictability, capacity, and capital efficiency.
Engineers retain complete architectural control. CAST synthesizes optimal transistor dimensions from first-principles physical equations rather than stochastic black boxes.
Solves multi-variable operating points (W, L, Vgs, Ibias) analytically using CSSM MOS modeling.
Simultaneously enforces constraints across process skews (SS, TT, FF), voltage fluctuations, and temperature extremes (-40°C to 125°C).
Outputs clean, foundry-compatible SPICE netlists that plug straight into existing layout, DRC, and LVS toolchains.
Transform volatile analog engineering OpEx into reusable intellectual property. Deliver mixed-signal tape-outs on schedule without ballooning simulator licensing bills or expanding design headcounts.
De-risks tape-out deadlines by 6–8 weeks. Missing a foundry shuttle deadline costs 3–4 months of market delay and millions in customer commercial commitments.
Recovers €100k–€200k in opportunity cost per engineer annually while cutting expensive simulator farm compute and license token exhaustion by up to 80%.
Re-synthesize analog IP across alternate foundries automatically. Avoid duplicating original NRE budgets and gain multi-sourcing pricing leverage.
How CAST transforms artisan transistor sizing into an automated, mathematically verified engineering flow.
Rather than treating circuits as black boxes or training predictive heuristics that hallucinate, CAST utilizes closed-form physical equations based on advanced MOS formulation. The solver evaluates multi-variable constraints simultaneously to converge on global optima in fractions of a second.
Because the solver evaluates the exact physical transistor equations, the generated operating point is mathematically provable—eliminating random Monte Carlo iterations and simulator licensing bottlenecks.
Design requirements are codified independently of specific silicon fab restrictions. When migrating to an alternate foundry or changing technology nodes, CAST re-synthesizes optimal dimensions for the target PDK automatically.
Complex analog topologies—operational amplifiers, bandgap references, low-dropout regulators (LDOs), and comparator stages—are synthesized and verified against multi-corner specs in minutes, freeing engineers for architectural innovation.
CAST does not require replacing your verified design rule checkers, extraction engines, or layout editors. It eliminates the manual sizing bottleneck before netlist verification.
