SYSTEM INTEGRATION

ASIC & SoC Design

Full custom silicon from architecture through tapeout: partitioning, RTL, verification, design for test, synthesis, static timing analysis, physical implementation and production transition. Programmes run across mature and advanced nodes, with the node chosen by what the application needs rather than by which number is smallest.

Architecture, RTL and verification.

DFT, synthesis and physical.

AFTER TAPEOUT

The part nobody plans for.

01

Bring-up planning

Written before parts return. Which tests, in which order, with which equipment, and what each failure would indicate.

02

Silicon bring-up

First power-on, interface validation, and the systematic isolation of anything that does not behave as simulated.

03

Characterisation

Performance across voltage, temperature and process corners, measured rather than inferred from the sign-off corners.

04

Test program

Production test development, coverage assessment and correlation between bench and tester results.

05

Yield analysis

Failure mode analysis and the design or process changes that follow from it.

06

Qualification

Reliability and qualification support appropriate to the target market and its service life.

COMMON QUESTIONS

What engineers ask before they call.

01

What does an ASIC design engagement include?

Architecture and specification, RTL design, functional verification, design for test, synthesis, static timing analysis, physical implementation and tapeout, continuing into bring-up, characterisation, test program development and yield analysis.

02

Do you work at advanced nodes only?

No. Node selection is driven by the application. Mature nodes from 180 nm to 90 nm remain correct for secure identity, analog and mixed-signal and long-lifecycle industrial parts, largely because of embedded non-volatile memory options, analog performance and supply horizon.

03

Can Faststream take over a design that is already partly complete?

Yes. A structured assessment of the existing RTL, constraints, verification state and physical progress comes first, so the handover starts from what is actually true rather than what the last status report said.
