Control.
Engineers stay in charge of AI-assisted and human-written RTL decisions.
Sigasi helps ASIC and FPGA teams across the semiconductor industry validate, understand, document, and review RTL in full project context, whether it is written by engineers, generated by HLS, supplied as IP, or produced by AI. SystemVerilog, Verilog, VHDL, and mixed-language projects are analyzed locally at interactive speed, whether the target is the digital hardware inside chipmaking equipment or an FPGA prototype of a future ASIC. Sigasi’s semantic analysis stays on your own infrastructure.

Engineers stay in charge of AI-assisted and human-written RTL decisions.
Teams understand project context, dependencies and design impact faster.
Technical leads apply coding rules and project-specific engineering discipline.
Developers catch issues earlier and reduce avoidable downstream friction.
RTL reaches review and integration in a more inspectable, maintainable state.

A change to one interface can reach across an SoC. A shared type changes, a wrapper retains an earlier definition, and a testbench still expects the old transaction. The code may look reasonable file by file. The integration question lives in the relationships between them.
Semiconductor teams need those relationships within reach while they work. Sigasi Visual HDL brings semantic HDL analysis into the workspace for SystemVerilog, Verilog, and VHDL, helping engineers investigate the configured project and prepare changes for review and verification.
ASIC development brings together internally developed IP, supplier blocks, shared packages, generated RTL, and verification code. Each target adds its own file selection, libraries, and configuration.
Sigasi helps engineers navigate from a reference to its declaration, inspect types and interfaces, and explore source-derived design structure. Supported checks provide feedback during editing. Modular Projects organize reusable targets and dependencies, making the context behind that feedback explicit. That helps a block designer investigate an interface change, an integration engineer understand an unfamiliar dependency, and a verification engineer maintain the environment around the design. The benefit begins before the next compile or regression.
FPGA prototypes let teams exercise selected ASIC behavior and develop software before manufactured silicon is available. They also introduce adaptations: memory implementations, wrappers, clocks, and debug logic can differ from the intended ASIC. Engineers must understand which source is shared and which belongs to the prototype. Sigasi helps inspect those boundaries and configurations; specialized prototyping tools handle partitioning, mapping, and implementation. Simulation and other verification establish the behavior the prototype must preserve.
RTL also serves the equipment used to make chips. ASML’s public engineering material describes digital electronics in EUV systems and FPGA work that spans design, verification, and product sustainment. That makes interface clarity and maintainable source relevant throughout the equipment lifecycle.
The same workspace capabilities help engineers investigate established control logic, assess a revision, and hand over the implementation with source-derived documentation. Exports can be regenerated as the design changes.
An AI-generated block can use an obsolete package or modify the wrong wrapper. Sigasi’s MCP integration gives agents access to project-aware analysis through the running extension. Licensed CLI workflows extend supported checks into automation. Engineers review the change and the verification evidence before it advances.
Deterministic source analysis answers a specific engineering question. Functional correctness, clock and reset behavior, timing closure, and sign-off require their own checks. Sigasi strengthens the workspace where engineers prepare RTL for that wider flow.

Sigasi parses the full project, not the open file: hierarchy, types, scopes, dependencies, interfaces and references across SystemVerilog, Verilog and VHDL. That model is what makes a review of supplier, legacy or AI-generated RTL an inspection rather than a reading exercise.
Compile at coding speed, so problems surface in the second they are written rather than at integration.
Fewer iterations, less wasted AI tokens, less review late in a program when work is most expensive.
RTL checked against your real project whether you or an AI agent wrote the code. You decide what moves forward based on facts, not hope.
