UVM register

UVM register

Why are Registers important?

These days Software addressable registers are present in large numbers in a SoC and IP. For instance, a typical VGA/LCD controller contains 560 registers, a larger design such as a microprocessor like UltraSparc contains thousands of registers. Registers need to be specified, designed, verified, validated, and debugged. All these activities add up to consume a significant amount of time estimated to be about 25% of the entire development effort.

UVM Registers

Fortunately, the industry can come together to solve the problem of register verification. The Verification IP technical (VIP-TC) committee under the auspices of Accellera has recently come up with the Universal Verification methodology – UVM library based on collaborative work between the big 3 EDA companies – Mentor, Synopsys and Cadence along with big customer companies such as Freescale, AMD, Cisco, Intel, etc. and smaller services companies.

The VIP-TC has included a register package in UVM that enables users to create a “shadow model” of the hardware’s register and memory map. This UVM register package contains classes for registers, register fields, register files, memories, blocks etc. This enables users to create the hardware register model.

UVM register is a base class library –
– Don’t have to write it yourself- like C/C++ libraries.
– Raise abstraction level
Use register names instead of addresses�Ц
– write (“dut.t1.register1”, data)

Equally important is the set of classes that help in automatically verifying the register model based on its specified properties.

Automatic Generators

What parameters should be looked at when selecting an automatic register generation methodology.
1. Buy Vs. build your own. If you do decide to build your own, remember the standards keep evolving and you would constantly need to update the generator.
2. Where are the register definitions located? Possible locations are :
Word, Excel, ASCII text files.
3. What outputs besides UVM need to be generated?
Users may have legacy environments such as OVM, VMM, or it may now be required to generate IP-XACT. RTL and C/C++ class files for firmware may also be required.
4. Verification team’s comfort factor in using a vendor tool that makes them re-enter the register spec in its special language or GUI.

IDesignSpec

IDesignSpec provides the most thorough and complete set of functionality in register management. Engineers don’t need to spend countless hours chasing register bits through the design, verification and validation process. Instead, they describe the register map once and for all, in a document, and that is considered “golden”. All files required by downstream processes are generated from that single source. This improves the engineers’ productivity and quality of results.

With IDesignSpec, users can describe the entire register map right in their document. This “live” document automatically generates classes and structures compliant with UVM register package. Other outputs such as RTL, C/C++ headers, IP-XACT etc. are also possible. Running in either interactive or batch mode, users can transform existing IP-XACT to UVM register classes or others.

IDesignSpec provides design teams a way to capture and extract register specifications within a design specification document. This methodology fits right into any system that users may already have in place. IDesignSpec can read in IP-XACT, SystemRDL, XML and CSV files with register data and generate SystemVerilog files that form input to the UVM based register verification environment.

Creating registers by hand is no fun, it as a laborious and error prone process. Use IDesignSpec to capture the specifications and the register information and generate all design and UVM based verification code from it. It is available as a plug-in for editors and spreadsheet tools (Word or Excel or OpenOffice.org) and enables users to embed register information right inside the functional specification.

Disk Cleanup Tool Role and Benefits

Disk Cleanup Tool Role and Benefits

Performing a Disk Cleanup can keep your Windows environment clean and running efficiently by deleting files that are no longer in use by you or the computer. Although it’s possible to keep individual tabs on the files the Disk Cleanup utility targets, it’s far easier to use this utility on a regular basis to identify and delete the files at the same time. Using Disk Cleanup won’t necessarily speed up your computer, but if temporary files are piling up beyond reasonable levels, this utility will help to address potential problems caused by their presence.

Effects of Temporary and Deleted Files

• Like most computer users, you likely don’t have the time or patience to constantly inspect your hard drive for files that can or should be deleted. But Windows has a knack for accumulating files over time that the operating system no longer requires. For example, when you install software, Windows often places certain files in a temporary location with the intention of deleting those files when you reboot your computer or at another specified time. Occasionally, Windows fails to delete those files, in turn consuming hard drive space and creating conflicts with other system components. Files can also accumulate on your hard drive when you delete them. When you delete files, they are sent to the Recycle Bin, where they remain until you empty it or use Disk Cleanup. Like temporary files, it’s easy to overlook the presence of files in the Recycle Bin, and those files can accumulate to massive storage levels over time.

Benefits

• The most immediate benefit of using Disk Cleanup is freeing valuable hard drive storage space. Modern hard drives offer plenty of storage, but this entices users to store massive files, including video and other media-related content. Deleting those files will not free up hard drive space until you empty the Recycle Bin or use Disk Cleanup. Likewise, temporary files (including temporary Internet files) can balloon to sizes in the hundreds of megabytes or more, potentially decreasing Windows’ ability to perform efficiently.

Usage

• With Disk Cleanup, Microsoft created a tool that’s simple and fast to use. The interface lets you select the type of files to delete, including temporary Internet files, files in the Recycle Bin, standard temporary files and others. When you select the files you want to delete, Disk Cleanup also shows you the amount of disk space you will gain after the utility deletes the files.

Considerations

• Using Disk Cleanup is not the last word in deleting temporary and other unused files from your system. This utility is unable to determine whether files residing on your Windows Desktop or in your personal folders are useful to you, so it’s up to you to occasionally scour your folders to identify potential candidates for deletion. Disk Cleanup also deletes temporary Internet files used only by Internet Explorer. If you use another browser, be sure to use that browser’s tools for deleting temporary files.

Warning

• Before selecting every deletion category in Disk Cleanup, carefully inspect the categories to ensure you’re not deleting files you might need.

Delete Restore Points

• If you configured the system restore feature to create restore points regularly, you might not realize these are eating plenty of hard drive space. You can use Disk Cleanup to easily remove restore points you no longer need. When using this option, Disk Cleanup will ask if you’d like to delete all but the most recent restore point. If your system runs without problems, this is generally a safe action to take.

First, let’s see what SharePoint is and how it can help you. SharePoint is basically an enterprise information portal, developed by Microsoft. It can be easily be configured to run Internet, Intranet, and Extranet sites and allows people and teams to collaborate. Whether you need to communicate and collaborate with your coworkers, your team, or your CEO, located a floor up or at the other end of the globe, you need SharePoint! This system is composed of Windows SharePoint Services (WSS) and the SharePoint portal. Individuals, small companies, and teams usually use Windows SharePoint services, while medium to large companies need the SharePoint Server.

Growing companies need more space for their files and documents and will soon loose track of them. This is why SharePoint allows you to both store and share all your files in a central site. With this new system, sending files through email is outdated. Now all team members have easy access to a single location where the files are stored. In today’s world, work is conducted in multiple locations. Whether you have employees in different parts of the county or even world, or working at home, SharePoint allows them to collaborate and communicate fast and easy. According to various surveys, the average employee spends between 20 and 30 percent of his or her time searching for information and data. SharePoint eliminates these loses by providing an easy way of searching through the hundreds of thousands of documents that were generated by the company. It is not easy to create and maintain sites and it can e very time consuming. This is why SharePoint can create sites for use on the Intranet in a matter of minutes. From discussion boards and meeting sites to departmental sites and document libraries, the system can have them ready in no time.

Microsoft SharePoint is the leader in enterprise information portals and it is growing rapidly. More and more people see the advantages of using this system. However, since creating and maintaining your own SharePoint server is very difficult and time consuming, we would recommend SharePoint hosting. You will be able to access all of the system’s features without having to worry about updates and technical issues.
