IC and SoC design: verification and integration
chipdesignmag.com helps working engineers connect an IC or SoC design question to explicit assumptions, runnable examples and inspectable evidence. Start with the boundary you need to check: a clock crossing, a power transition, an IP interface or a tool handoff. Keep documented capabilities separate from the behavior observed in a particular run.
Verify the transfer you actually need
A clock-domain crossing is a transfer problem before it is a choice of synchronizer. A level, an event and a coherent word have different requirements. The clock-crossing guide separates settling assumptions, pulse capture, glitches and multibit coherence, with original simulated examples and explicit limits on what digital simulation can show.
Use the power-domain guide when the boundary involves isolation, retention or reset order. Its plain RTL checks make the intended sequence observable. They do not replace a power-aware implementation flow or establish that physical isolation and retention cells are correctly inserted.
For a larger integration, the block-to-SoC guide connects software-visible actions with checks at the block and system boundary. A UVM framework is one part of a verification environment; the public standard and reference implementation do not supply a project’s requirements or complete its verification plan1.
Inspect evidence before integrating IP
The IP resource finder filters twenty pinned open-core records by interface, licence, collateral type and language. It links to repository evidence rather than assigning a readiness score. A null field means the relevant item was not verified in this audit, so it should become a follow-up question instead of an assumption that a file does not exist.
The companion integration evidence table explains how to use clock/reset descriptions, register information, drivers, constraints and verification collateral together. IP-XACT provides standardized descriptions for integration information, but a project’s use of that standard is something to establish from its actual records2.
For serial-link models, the IBIS-AMI reference separates package files, analysis settings and execution evidence. It is a documentation-based integration checklist, with no claim that a vendor model has been loaded or a channel result reproduced.
Make tool results reproducible
The simulator observations preserve identical original source bytes, commands and literal outputs across two pinned tools. Interpret differences with their language settings and initialization options; the table is not a compliance ranking.
Use the EDA handoff table to inspect documented inputs and outputs across twenty tools. Then use the reproducible handoff guide to identify the files and configuration behind a result. A matching hash confirms byte identity, while an executed test checks the specific behavior its assertions cover.
