AI-native IC design

10× faster IC design.

ParallelCascade designs analog, digital and mixed-signal integrated circuits with AI agents. For a defined scope, agents carry the work from specification to verified implementation, and a ParallelCascade engineer owns the architecture, the constraints and the sign-off.

The 10× applies to defined scopes with a written specification and acceptance criteria, not to open-ended research.

ScopeAnalog, digital and mixed-signal blocks, from specification to verified implementation.
Multi-PDKHands-on experience in SKY130, UMC180 and XFAB180.
Sign-offArchitecture, constraints and acceptance owned by an engineer.

Analog, digital and mixed-signal. One agentic flow.

The same flow serves each discipline: an executable specification, design iterations checked by simulation and verification, and layout driven by DRC/LVS results. Agents do the iterating; an engineer reviews every change and owns sign-off.

Analog IC

Analog IC design

Circuits where power, noise, area and robustness decide the outcome, iterated against the specification across every corner.

  • Specification turned into executable checks
  • Schematic iterations confirmed by simulation
  • Layout driven by DRC/LVS results
Digital IC

Digital IC design

Digital and control logic written, verified and implemented against a written specification, ready to integrate.

  • RTL and testbenches from the specification
  • Verification and implementation loops
  • Standard-cell implementation through DRC/LVS
Mixed-signal

Mixed-signal IC design

Analog and digital blocks designed together, with the interface between them specified and verified rather than assumed.

  • Analog and digital co-verification
  • Interface and timing checks at the boundary
  • One sign-off for the whole block

Multi-PDK experience

IC design experience in three process design kits: the flow adapts to each PDK's rules, models and verification decks.

Only the PDKs are named. Client names, circuits and silicon results stay confidential.

Illustration: simulation curves from successive design iterations, the last one settling inside the specification mask.
Where the 10× comes from

Agents run the iteration loop.

Design, simulation and DRC/LVS iterations run back to back against the specification, instead of waiting for the next manual pass.

Illustration: layout of a mixed-signal block, analog and digital halves, selected for an engineer's review and sign-off.
Where the judgement stays

Engineers own architecture and sign-off.

Agent output only counts once simulation, verification and an engineer's review agree with the specification.

Entry offer

Agentic IC Design Sprint

One defined block or subsystem, taken from specification to verified implementation in a fixed scope. The price is set per milestone before work begins, and each milestone closes against acceptance criteria agreed in writing.

1

Scope freeze: specification, PDK, corners, deliverables and acceptance criteria agreed, with the price of each milestone.

2

Design and verification: agent-driven design iterations, with simulation and verification results reported against the specification.

3

Verified implementation: DRC/LVS-clean layout in the agreed PDK, post-layout verification results and handover of every design file.

Not an hourly engagement and not a generic review: a fixed scope, a price per milestone and a defined result.

Example Sprint plan: three milestones, each with a fixed price and acceptance criteria.

Explicit inputs. Written acceptance.

A Sprint starts once the inputs are on the table and closes once the acceptance criteria are met. Both are agreed at scope freeze.

Inputs

What the Sprint needs from you

  • A written specification: function, performance targets, power and area budget.
  • The PDK and process options, with access to the design kit under its licence.
  • Operating conditions and corners: supply, temperature and process.
  • Interfaces and integration constraints: pins, protocols, floorplan or the surrounding chip.
  • Existing material, if any (schematics, RTL, testbenches), plus the deliverable format and tools.
Acceptance

How each milestone is accepted

  • Simulation results meet the specification table across the agreed corners.
  • Verification passes: testbenches for analog, regression and coverage targets for digital.
  • The layout is DRC- and LVS-clean in the agreed PDK, with post-layout results reported.
  • An engineer has reviewed every change and signs the milestone report.
  • Design files, scripts and reports are handed over in the agreed format.
Start with a defined scope

Have a block that needs to be designed and verified?

Send the specification or a short description, the PDK and the deadline. If it is a fit, the first step is a scoped Agentic IC Design Sprint.

What happens next

  1. Send 5–10 lines about the block, no polished brief needed.
  2. ParallelCascade replies if there is a fit, usually within two business days.
  3. Scope freeze: inputs, acceptance criteria and a price per milestone, agreed before work begins.
  4. An NDA is available before you share detailed material.
