Open Source VHDL Verification Methodology (OS-VVM™)
Open Source VHDL Verification Methodology provides the VHDL community with advanced verification methodologies, including functional coverage, "Intelligent Coverage" (aka coverage driven randomization) test generation, and constrained random test generation. It is based on a set open source of packages. While it is package based, it offers a similar capability and conciseness to other verification languages.
Like other verification languages it is all about the methodology.

CoveragePkg: Functional Coverage Collection and Reporting
CoveragePkg simplifies the modeling and collection of high fidelity functional coverage, both point and cross coverage. It provides a number of methods for interacting with the coverage data structure. One unique feature, "Intelligent Coverage", provides for randomization across coverage holes is a foundation of the methodology.
In OS-VVM, "Intelligent Coverage" provides the top level shaping of the stimulus and naturally balances the randomization solution without the need for a solver. Since it only randomly chooses actions that are holes in the coverage, "Intelligent Coverage" helps minimize the number of test cases generated to achieve complete coverage - resulting in fewer simulation cycles and a higher velocity of verification.

RandomPkg: Constrained Random Verification with VHDL
RandomPkg provides a basis for doing constrained random verification in VHDL. It provides functions for uniform randomization in a range or in a set, and for discrete, weighted distributions. Constraints are formed by calling randomizations within sequential code.
Within OS-VVM constrained random is used further refine the initial randomization done over the holes in the functional coverage.

Rev 1.1 |
CoveragePkg: Functional Coverage Collection and Reporting
Contains subprograms that simplify functional coverage modeling and collection
for single object coverage (point or item coverage)
and multiple object coverage (cross coverage).
Version 2.1 (and 2.0) implements the coverage database in a
shared variable/protected type and increases the effiency of the
implementation.
Supports randomizing across missing coverage.
