Full-custom and library characterization
Transistor-level design, where it moves the whole chip.
Full-custom applies to the critical datapath blocks; the rest of a chip uses a standard tool flow. From custom cells, library characterization and re-characterization to hand-crafted netlists, custom clock trees and manual place and route, our method has nine stages, and each closes with evidence a customer can read.

Library characterization
Standard cell library characterization, including ultra-low-voltage libraries
FinFET tape-outs
The full-custom method on real silicon, from an MPW in our founding year to a full mask set the next year
Nine stages
From fit and partitioning to silicon correlation
What we do
One team for the chip and everything it takes to ship it.
Full-custom and library characterization
Custom cells, library characterization and re-characterization, hand-crafted netlists, custom clock trees and manual place and route, for the blocks that decide a chip's performance.
Custom AI chips
Accelerators shaped around your models, your power budget and your cost target.
ASIC design services
Architecture, RTL, verification, DFT and physical design, as a full flow or one stage at a time.
Production and supply
Wafers, test, assembly and logistics planned as one schedule.
Engagement models
Hand over as much of the flow as suits your team.
Four starting points. In each, Chipchain owns every stage from the hand-off onward.
| Specification | RTL | Verification | Physical design | Tape-out | Production | |
|---|---|---|---|---|---|---|
| Spec-inYou bring the requirements; we deliver production silicon. | Chipchain | Chipchain | Chipchain | Chipchain | Chipchain | Chipchain |
| Netlist-inYou hand over a verified netlist; we close the design and build it. | Your team | Your team | Chipchain | Chipchain | Chipchain | Chipchain |
| GDS-inYou hand over signed-off layout; we tape it out and run production. | Your team | Your team | Your team | Your team | Chipchain | Chipchain |
