Latest commit. Latest commit 99d Apr 30, It then shows how to verify a cluster design a APB subsystem into which the UART gets integrated along with other design components viz.

Thus, it ensures that all exiting eRM compliant environments need not to be re-coded to work with an UVM compatible environment. Usage of UVM-e Scoreboard package is also included in this release.

Code Coverage is good for checking if implementation code has been tested, but cannot guarantee functional accuracy. Currently, functional accuracy is guaranteed using pre-planned directed tests, auditing the test code and auditing the log files.

This is not scalable as designs get complex. We will be using UVM to describe the stimulus space to look for anomalous behavior. The DER is responsible to audit the flow with the focus on design safety.

The managers are trying to meet the customer requirements with shorter design schedules and optimal resources. The designers want to accurately capture the design intent using the tools provided. It is not a specific phase of development, but rather occurs throughout the design flow from the earliest models to the final testing of the component in the system.

The primary objective is to ensure that a design performs the function specified by its requirements and that it satisfies agreed-upon completion criteria.

What is OpenCores?

Safety critical DAL A and B devices require that the verification be carried out independent of the design. Code Coverage is a good metric for determining if the design implementation code statements, conditional blocks or FSM coding structures are exercised by simulation.

But Code Coverage will not assure the functional accuracy, integrity of a reusable IP block or a bus protocol. This leads to writing too many redundant tests and wasted simulation cycles. See Figure 1. Did the higher Code Coverage mean the design is functionally accurate? Did the manual audit miss functionality? Did the larger design state space get exercised to look for any anomalous behavior?

Is there unnecessary testing wasting simulation cycles? When planning for sufficient elemental analysis at every stage of the design flow one needs to confirm things identified in Table 1.

DERs would like a tool that showed the spec in an executable format for stimulus and response. This can reduce the time currently spent on manual audit. And designers would like to use the latest methodology to make their delivery more reliable and robust. The testing needs to be pre-planned to cover the required modes and configurations, but it also needs to make sure other unused configurations and modes have pre-determined safe behavior. To guide the stimulus we can use Functional Coverage.

It is developed by a conglomeration of companies and independent developers. It is based upon various precursors of the technologies including proprietary technologies developed and deployed for complex hardware verification over the decades.

It is supported by all the major simulation tool vendors and is widely exercised by thousands of projects across the industry. UVM testbench has the similar goals of applying test vectors and measuring the response as shown in Figure 1.

The major difference with UVM is that the structure of UVM testbench is component-based and uses improved object-oriented syntaxes added in the SystemVerilog language.

This allows plug-n-play and reuse as shown in Figure 1. We will also highlight how these aspects help a DO type of project. As seen in the figure, the total number of input bits including the operands and operations is bits. From a testing perspective we cannot possibly test all the bit input data bit combinations 2 It usestest cases for each operation and rounding mode amounting to about two million stimulus vectors.
