Mixed-signal verification for hardware teams
Verilog and SPICE in one browser workspace
Run mixed-signal verification with tenant isolation, team invites, and auditable AI diagnostics — built for hardware startups and product teams, not coursework-only.
Testbench passed. Output q toggles cleanly on every rising clock edge with no metastability.
Cloud simulation
Verilog + SPICE in one workspace
- Upload digital and analog designs — single files or multi-file archives with a named top module or cell.
- Managed simulators run jobs in a browser-native tenant workspace — no local toolchain to install.
- Review VCD waveforms, full logs, and clear pass/fail the moment verification finishes.
Drop .v, .sp, or .zip archive

Auditable diagnostic AI
Understand failures, not just read logs
- Turn dense simulator output into plain-language diagnostics tied to each run.
- See how signals behaved, why a testbench passed, or what caused a failure — with usage quotas and disclosure controls.
- Production AI features are flag-gated pending counsel review.
- q toggles on every rising clk edge after reset_n deasserts — no metastability observed across 1,024 cycles.
- Testbench assertions passed at t=10.4 µs. Counter reached expected wrap value without X-propagation.
- No timing violations or unexpected Z-states in the monitored bus.

Projects & teams
Tenant controls for product teams
- Group related runs into projects to keep mixed-signal verification organized.
- Invite teammates with owner, admin, and member roles — built for hardware startups and teams of 5–20 engineers.
- Each workspace is tenant-isolated with plan-aware entitlements and least-privilege access.

Run history
Auditable history for every run
- Each run is recorded with status, timing, logs, and waveforms.
- Revisit any past simulation and its AI diagnostic at any time.
- Reliable history for design reviews, handoffs, and reproducible verification.
