PHASE 03PROTONSIM
Prototype

Measure the workload before freezing the machine.

ProtonSim is a workload and architecture modeling direction for connecting transformer behavior to compute, memory, and dataflow decisions.

TRACEABLE OUTPUTArchitecture decision reportAssumptions + model + recommendation + limitations
01WHY SIMULATE FIRST

RTL is an expensive place to discover the wrong architecture.

A workload model can expose operator mix, data movement, arithmetic intensity, utilization limits, and prefill/decode differences before implementation choices harden.

02WORKLOAD CONTRACT

Define what the system is expected to execute.

Model family, parameter envelope, batch, context, quantization, operator coverage, and execution phase form the first traceable input.

03OPERATOR CHARACTERIZATION

Break the model into work and movement.

GEMM, GEMV, reductions, normalization, positional operations, elementwise work, weight reads, activation traffic, and KV-cache traffic are characterized separately.

04ROOFLINE + BANDWIDTH

Compute throughput matters only when data can arrive.

Roofline-style analysis is intended to compare arithmetic demand with local and external bandwidth limits without presenting unvalidated performance results.

05DESIGN-SPACE EXPLORATION

Sweep the decisions that materially change the machine.

Candidate sweeps include memory bandwidth, scratchpad capacity, vector width, vector lanes, matrix dimensions, dataflows, and prefill/decode policy.

06DECISION TRACEABILITY

Every recommendation should point back to workload evidence.

The intended output is a versioned architecture report that links assumptions, model inputs, analytical results, and the decision they support.

07STATUS + LIMITATIONS

Illustrative controls are not benchmark results.

The current website demonstrates the intended design space only. Accuracy, cycle correlation, supported models, and performance remain to be validated before publication.
