← All services Service 01 / Algorithm to RTL

Your MATLAB or C algorithm, converted to synthesizable RTL.

Floating-point reference model to fixed-point implementation to production RTL, with dynamic range analysis behind every word-length decision and testbenches that prove the hardware matches your algorithm bit for bit.

The conversion process

Algorithm to hardware, with the numerics proven at each step.

The risk in this work is never the syntax. It is quantization: a fixed-point model that drifts from your algorithm in ways nobody notices until the hardware is in the field. Every stage below is verified against the one before it.

01

Golden reference

Your MATLAB or C floating-point algorithm becomes the reference model, with a test vector set that defines correct behavior.

02

Dynamic range analysis

The reference is instrumented and profiled over real stimulus to find the actual range every internal signal reaches.

03

Fixed-point model

A MATLAB fixed-point version with word lengths, rounding, and saturation chosen from the measured ranges, not guessed.

04

RTL implementation

Synthesizable VHDL or Verilog that matches the fixed-point model exactly, written to production standards.

05

Verification

Testbenches and test cases that compare RTL output against the reference and report the error metrics you care about.

Pricing

Start free, then pay by project size.

Your first dynamic range analysis is free, with no card and no commitment. Conversions are priced by the size of the algorithm. Larger than the listed tiers? Send it over for a free scope.

Dynamic range analysis

Word lengths chosen from measurement, not margin.

Guessing bit widths costs you either accuracy or area. Profiling the algorithm over representative stimulus tells you exactly how many integer and fractional bits each signal needs.

  • 01
    Signal range profiling. Every internal node instrumented and tracked over the full test vector set, including the accumulators where growth actually happens.
  • 02
    Integer and fractional split. Bit allocation derived from measured minimum and maximum values, with guard bits where the analysis shows they are needed.
  • 03
    Overflow strategy. Saturation or wraparound decided per signal, deliberately, with the consequence documented.
  • 04
    Rounding mode. Nearest, floor, or convergent chosen where it matters, so truncation bias does not accumulate through the datapath.
  • 05
    Quantization error budget. An explicit accuracy target, measured as SNR or maximum absolute error against the float reference.
  • 06
    Word-length optimization. The area and accuracy tradeoff made visible, so you can spend bits where they buy something.
Range analysisMATLAB
% Ranges observed over the full test vector set % acc [-3.9971, 4.0128] -> Q3.13 (+guard) % coeff_b [-1.0000, 0.9998] -> Q1.15 % y_out [-1.8442, 1.8517] -> Q2.14 % Fixed-point type: explicit rounding and overflow T = numerictype(1, 16, 13); F = fimath('RoundingMethod','Nearest', ... 'OverflowAction','Saturate'); acc = fi(0, T, F); % Accuracy against the floating-point golden model snr = 10*log10( sum(y_ref.^2) / ... sum((y_ref - double(y_fix)).^2) ); % snr = 78.4 dB spec: > 72 dB PASS
Every word length we pick is traceable to a measured range and an accuracy target. You get the analysis, not just the result.
Verification

Proof that the hardware does what your algorithm does.

A conversion you cannot verify is a conversion you cannot trust. Every delivery includes the testbenches and test cases that demonstrate equivalence.

Bit-accurate comparison

RTL output checked against the fixed-point model sample by sample, so any divergence shows up immediately rather than in silicon.

Directed corner cases

Test cases targeting saturation limits, zero crossings, maximum gain, and the input patterns that stress your specific algorithm.

Real-world stimulus

Your own captured data run through both models, because random vectors rarely exercise the ranges that matter in practice.

Reported error metrics

SNR, maximum absolute error, and bit-growth summaries against the float reference, measured rather than asserted.

What we accept

Bring the algorithm in whatever form it exists.

A working floating-point implementation and a set of representative input data is enough to start. A written spec helps but is not required.

What you receive

Five deliverables, not just a folder of RTL.

  • A
    Range analysis report. Measured ranges per signal, chosen word lengths, and the reasoning behind each one.
  • B
    MATLAB fixed-point model. A runnable intermediate you can experiment with independently of the hardware.
  • C
    Synthesizable RTL. Production VHDL or Verilog, parameterized and documented to the same standard as our design work.
  • D
    Testbenches. Self-checking benches comparing RTL against the reference, ready to run in your simulator.
  • E
    Test case suite. The directed and real-world vectors, kept so you can re-run them as a regression after future changes.
Why it matters

Where this saves you.

Quantization bugs are brutal

A fixed-point error does not crash. It quietly degrades accuracy or wraps once every million samples, and it is found late and debugged slowly.

Algorithm people should not fight bit widths

Your DSP or ML engineers stay on the algorithm while the numerics and hardware mapping are handled by people who do it constantly.

Area you do not waste

Oversized word lengths are the most common source of a design that will not fit. Measured ranges keep the datapath as narrow as it can safely be.

What usually comes next.

Conversion is the first stage. The services below carry the result forward.

Send us the algorithm.

A floating-point model and some representative input data is enough for us to scope the conversion and quote it.
