Truechip’s DisplayPort 2.0 Verification IP (VIP) Solution

Integrating IP to build SoCs has been consistently on the rise. Growth in complexity and meeting time to market pressures are some primary drivers behind this phenomenon. Consequentially, the IP market segment has also been enjoying tremendous growth. While this is great news for chip design schedules, it does highlight the increased demand for quick, easy and accurate verification. Without a time and cost efficient way to verify an IP solution, the cost of verifying can end up being higher than the cost of developing the IP itself. And an SoC’s development schedule would be adversely impacted. Naturally, the Verification IP (VIP) segment of the IP market has seen high growth rates.

There are IP verification solutions offered by a number of companies. One company that was introduced in late 2020 to the SemiWiki audience is Truechip. Founded in 2008, Truechip characterizes itself as the Verification IP Specialist. It offers an extensive portfolio of VIP solutions to verify IP components interfacing with industry-standard protocols integrated into ASICs, FPGAs and SoCs.

Salient Aspects of Truechip’s VIP Solutions

Truechip’s Verification IPs are fully compliant to standard specifications and come with an easy plug-and-play interface to enable a rapid development cycle. The VIPs are highly configurable by the user to suit the verification environment. They also support a variety of error injection scenarios to help stress test the device under test (DUT). Their comprehensive documentation includes user guides for various scenarios of VIP/DUT integration. Truechip’s VIP solutions work with all industry-leading dynamic and formal verification simulators. The solutions also include Assertions that can be used in formal and dynamic verification as well as with emulations.

And their solutions come with the TruEYE GUI-based tool that makes debugging very easy. This patented debugging tool reduces debugging time by up to 50%.

Truechip’s DisplayPort 2.0 VIP Solution

One interface IP that is gaining lot of attention these days is the DisplayPort IP. Truechip has been supporting the Display market segment with VIP solutions for HDMI, HDCP and DisplayPort. They recently expanded their portfolio with the addition of DisplayPort 2.0 VIP solution. Their DisplayPort 1.4 VIP has a long track record within the customer base. Their DisplayPort 2.0 VIP has brought lot of upgrades to keep up with the enhancements from DisplayPort 1.4 to 2.0. The following Figure depicts a block diagram of the corresponding VIP environment.

The DisplayPort 2.0 VIP is fully compliant with Standard DisplayPort Version 2.0 specifications from VESA. Nonetheless, it is a light weight VIP with easy plug-and -play interface for a rapid design cycle and reduced simulation time. The solution is offered in native System Verilog (UVM/OVM/ VMM) and Verilog, with availability of compliance and regression test suites.
