This method starts the execution of the UVM phases, which controls the orderin which the testbench is built, stimulus is generated andthenreports on the results of the simulation. The top level class in an UVM testbench is usually known as the test class and this class is responsible for configuring the testbench, initiating the construction process by building the next level down in the hierarchy and by initiating the stimulus by starting the main sequence. For a given verification environment, the testbench hierararchy below the test class is reasonably consistent, and each test case is implemented by extending a test base class. The UVM testbench architecture is modular to facilitate the reuse of groups of verification components either in different projects horizontal reuse or at a higher level of integration in the same project vertical reuse. There are two main collective component types used to enable reuse - the env short for environment and the agent. The purpose of the agent is to provide a verification component which allows users to generate and monitor pin level transactions.

DNS: Right-click ovm-mgr and then click Manage Network. In the Confirmation window, click Close. Create a Server Pool A virtual server pool contains one or more virtual servers and guest virtual machines.
A virtual server can belong to one and only one virtual server pool at a time. Guest virtual machines and resources are also associated with the server pools.
A clustered server pool may contain several virtual servers sharing a storage system. VMs within a clustered server pool may be live-migrated from one virtual server to another. We will now create a nonclustered server pool using the single Oracle VM server we have. In the "Search and Select: Targets" window, select the ovm-srv.
Figure 21 - Select the ovm-srv. Make sure Auto Refresh is set to 15 Seconds. Wait for the job to finish look for Status to show Succeeded. Click View and then Expand All to see all components. You should now see the newly created pool called devpool.
Figure 23 - Newly created pool Create a Zone A zone is used to group related cloud resources together. Cloud zones can be created based on location or software lifecycle status and for grouping resources according to a cost center or for metering and chargeback purposes.
Typically, a zone can cover a department or possibly a small data center. In the Infrastructure Cloud home page, right-click ovm-mgr, and then click Create Zone. Click to add a pool to the zone. Figure 25 - Select the devpool line Click Select. Create a Storage Repository A storage repository is virtual disk space on top of physical storage hardware, which is made available to the Oracle VM Servers in a server pool or in various server pools.
It defines where Oracle VM resources may reside. Resources include virtual machines, templates for virtual machine creation, virtual machine assemblies, ISO images, shared virtual disks, and so on.
Right-click ovm-mgr, and then click Manage Storage Repository. In the Create Repository window, do the following: Enter devrepo as the name of the repository.
Select Physical Disk as the storage type. This will open the LUN Selector window. Click next to Server Pool to choose the server pool to use. This will open the "Search and Select: Targets" window. Select the devpool target and click Select. Figure 29 - Select the devpool target Click OK to create the repository. You should now see the newly created repository called devrepo. In the "Storage Repository Details: devrepo" window, click Present. In the Select Targets window, do the following: Select the devzone checkbox.
Figure 33 - Select the devzone checkbox In the Present Servers window, you should now see the ovm-srv. Click Present. Figure 34 - Select ovm-srv. You can use assemblies provided by Oracle or create your own assemblies using Oracle Virtual Assembly Builder.
This assembly was imported into the Oracle Software Library before the lab or you imported it by following Appendix A. We will now import it to the storage repository. In the Storage Repository window, click the devrepo repository.
In the "Storage Repository Details: devrepo" window, click the Assemblies tab. Click Import. Leave the default value for Storage Default. Note: Because of the poor performance of the x86 physical machine laptop , you might get the error Unable to retrieve the component type for the Selected Component. If so, wait for a few seconds and click Continue again. The error should disappear. In the "Import: Schedule" window, do the following: Leave the default values. Click Finish to start the import immediately.
The import will take a few minutes. To save time, we will continue to the next steps. The import of the assembly should be finished before we actually use the assembly with the self-service user. We will now authorize some self-service users to deploy their own servers on the zone we created using the assembly we imported.
We will also set up some resource limits to prevent a specific user from consuming all resources. In the Machine Sizes section, click Create. The first disk is normally reserved for the OS and its size is Leave the default value No restriction for Request Duration. Click next to Folder Name to select the Software Library top level folder.
Click Apply. In real life, it is recommended that you deploy the Oracle Enterprise Manager agent. In the left panel, click Roles. In the Roles section, click Assign Quota to Role.

Open verification methodology cookbook
Glasser, Open Verification Methodology Cookbook Functional verification is an art as much as a science. It requires not only creativity and cunning, but also a clear methodology to approach the problem. The Open Verification Methodology OVM is a leading-edge methodology for verifying designs at multiple levels of abstraction. It brings together ideas from electrical, systems, and software engineering to provide a complete methodology for verifying large scale System-on-Chip SoC designs.
