3.4 External Tools: Unit Linting in Riviera-PRO Riviera-PRO offers the design rule checking capabilities of ALINT-PRO directly within the tool through unit linting. Running the feature within the design tool's GUI will perform design checks according to the generated ALINT-PRO project, and those violations will be displayed in Riviera-PRO's console and HDL editor in the form of various warnings and messages. Modification of a design's policy is facilitated through additional context menu items within the Design Browser, which allows launching of ALINT-PRO into the relevant views for modifying policy or waivers.
