0-In® CheckerWare®

Designers are rapidly adopting assertion-based verification (ABV) as the means to improve overall verification quality. The fastest way to adopt ABV is through proven assertion libraries.  Assertion libraries allow designers to simply select from a library the various design intent checkers and protocol monitors and add them to the design without the need to learn new languages and/or spend a lot of effort in creating these checkers and monitor themselves.

The 0-In® Checkerware® Assertion Library dramatically improves the productivity of assertion-based verification.  It consists of the industries largest set of design intent checkers and monitors for a variety of industry standard protocols. All the assertions can be used in simulation, emulation and/or FPGAs and formal verification.

• Design intent checking assertions include:
• user (custom, mutex, same_bit, timeout)
• basic (driven, known, known_driven, three_state)
• coverage (coverage, xproduct_bit_coverage, xproduct_value_coverage)
• interface (assert_follower, assert_timer, bus_driver, change_timer)
• control (channel_data_integrity, multi_port_memory_access)
• interface and control (assert_together, multi_clock_fifo, scoreboard)
• datapath (arithmetic_overflow, data_used, encoder, serial_to_parallel)
• Protocol monitors include:
• Standard buses: AMBA (AHB, APB, AXI),  OCP,
• Interfaces: PCI, USB 1.1, PCI-X, USB 2.0, SATA, 10G Ethernet, SCSI, 
• Memory: AGP, DDR SDRAM, SRAM, DDR-II SDRAM, , SigmaRAM,  
• Networking: UTOPIA, QDR, SPI4-2, , POS-PHY Level 2

Benefits

• Automatic coverage collection to quickly identify verification holes
• Total interoperability with all standard assertion formats, including PSL, SVA, and OVL
• Advanced management of checkers and assertions throughout design lifecycle
• Unique design inference capability for ease of adoption and maintainability of assertions

Supports simulators, emulators, and formal verification tools from Mentor Graphics and third parties
