Semiconductor engineering

From wafer to working platform

Tyantra Technologies delivers specialized semiconductor engineering consulting across SoC validation, CPU functional validation, post-silicon debugging and high-speed interface validation.

We help semiconductor businesses improve silicon quality through systematic testing, engineering analysis and practical validation methodologies.

Services

Four areas of validation work

Specialised capability for teams bringing up and qualifying silicon, from first power-on to a platform that passes.

SoC and CPU validation

Processor functional testing, cache, memory subsystem and platform validation.

Cores · cache · memory subsystem · platform

Post-silicon debug

Silicon bring-up, failure analysis, debugging and root-cause investigation.

Bring-up · failure analysis · root cause

High-speed interface validation

PCIe, DDR, CXL and Ethernet functional validation.

PCIe · DDR · CXL · Ethernet

Timing chip QA

Timing functionality, clock synchronization and engineering quality assurance.

Approach

How an engagement runs

Each project follows the same path, so you know what you get and when.

  1. Step 1

    Scope

    Agree the silicon, the features under test, the platform and the exit criteria.

  2. Step 2

    Bring up

    Get the board, firmware and bench stable enough to test with confidence.

  3. Step 3

    Validate and debug

    Run the test plan, reproduce failures and trace each one to its root cause.

  4. Step 4

    Report and hand over

    Deliver findings, failing cases and the automation, so your team can rerun everything.

Experience

17+ years across CPUs, SoCs and timing silicon

From a start-up x86 design to GPU drivers, server firmware, multicore SoCs and timing chips, the work has always been finding what fails, and why.

Company names show where the work was done. They do not imply endorsement.

Montalvo Systems · x86 CPU · 2006–2008

Defects found in a brand-new x86 design

Detected a defect in the write-combining buffer's non-temporal instruction handling, and another where several virtual addresses mapped to one physical address under MOVNT instructions. Wrote test suites for all x86 system-level instructions.

AMD · Processor validation · 2012–2013

Microcode debugged on emulation

Validated new ISA instructions and used Cadence Palladium, with save, restore and checkpoints, to debug microcode logic. Found defects in the random test tools and simulator during silicon bring-up.

NVIDIA · GPU software · 2008–2009

GPU channel switching validated

Wrote C++ tests for GPU channel switching, root-caused driver failures with Windows debuggers and gdb, and built overnight regression runs on fast models with emailed reports.

Honeywell · Hard real-time · 2015–2016

Processors characterised for real-time use

Assessed processor behaviour for hard real-time applications, including the feasibility of cache colouring and the effect of system-memory interference across several microprocessors.

Infineon · Post-silicon · 2016–2019

A new way to validate the whole clock tree

Proposed and built a methodology to traverse and validate the complete clock tree, and verified customer-driven clock ratios of the SoC using testbench automation.

Intel · Silicon validation lead · 2021–2025

Regression triage at team scale

Led a team through daily regression monitoring, triage and debug of automation results, reproducing failures for debug, and found a data-inconsistency flagging issue in a validation tool.

About

Hands-on validation, led by an engineer

Tyantra Technologies is led by a lead SoC validation engineer with more than 17 years in post-silicon work: multicore SoC debug, x86 and ARM processor bring-up, PCIe, DDR and CXL protocol validation, and IEEE 1588 timing systems.

You work directly with the engineer who does the testing, from the first test plan to the final report.
