HDL Studio

Hardware design inside VS Code: step through simulation time in both directions, read millions of signal transitions without waiting, and go from code to a programmed board.

The signal viewer showing the clock, reset, enable and counter waveforms of a design, with a time cursor placed on the ruler.
Every signal of the running simulation, ready to read as soon as it opens.
The debugger paused at 45 ns on a highlighted line of a counter design, with signal values, the call stack and breakpoints in the side bar.
Pause at any instant of the simulation and read every value at that moment.
The block design editor with its catalogue of blocks, a design checked with no problems, and the generated top level open beside it.
Assemble a design from ready-made blocks and generate its top level in one click.

What it does

The debugger shows the design at any instant of the simulation, forwards or backwards. The signal viewer opens millions of transitions without waiting. One command synthesises, implements and programs the board from the editor, and your assistant can run every step for you.

Where it fits

HDL Studio shares the account, licence and credits of every Soft Forge product, and its documentation lives on soft-forge.dev.
