Hi,

Is it possible to use a SystemVerilog package which is compiled into a library and then use it in a VHDL-2008 design file? Is such mixed-language flow supported?

I'm considering the latest versions of Incisive / Xcelium available today (Oct 2019).

Thank you,

Michal

I have been working on a an ASA 17.2 project for the last 6 months.

When I go to Project --> Settings, the settings window does not open. 

The tool indicates that a window is open, as I cannot click on anything else in the project. But it does not show the Settings window.

This has been happening only for the last 2 months. Before that it was working fine.

If I send the project to my colleague, the settings window shows up for him.

Hi, I am uploading a register class, which can be used for modeling hardware registers. I am uploading the source code and examples on how to run it. I also have a user guide which has all the APIs listed and explained. The user guide is ARV.pdf in the attached tar file. I have named the class ARV, which stands for Architect's Register View. It has got very good randomization and coverage features. Users have told me that its better than RAL. You can download it from http://verisilica.info/ARV.php
. There is a limit of 750KB in this cadence website. The ARV file is 4MB. That is why, I am uploading it at this site. I have a big pdf documentation and a doxygen documentation there. That is the reason for the bigger file size. The password to open the ZIP file is ovm_arv. I hope, everyone will use these classes.

Please contact me for any help.

// Einstein formulated this problem : he said that only 2% in the world can solve this problem
// There are 5 different parameters each with 5 different attributes
// The following is the problem

// -> In a street there are five houses, painted five different colors (RED, GREEN, BLUE, YELLOW, WHITE)

// -> In each house lives a person of different nationality (GERMAN, NORWEGIAN, SWEDEN, DANISH, BRITAIN)

// -> These five homeowners each drink a different kind of beverage (TEA, WATER, MILK, COFFEE, BEER),

// -> smoke different brand of cigar (DUNHILL, PRINCE, BLUE MASTER, BLENDS, PALL MALL)

// -> and keep a different pet (BIRD, CATS, DOGS, FISH, HORSES)


///////////////////////////////////////////////////////////////////////////////////////
// *************** Einstein's riddle is: Who owns the fish? ***************************

Hi Everyone,

Many of you would have heard about the Cadence Stylus Common UI and are wondering what it is and what the advantages might be to use it versus legacy UI.

The webinar answers the following questions:

• Why did Cadence develop Stylus UI and what is Stylus Common UI?
• How does someone invoke and use the Stylus Common UI?
• What are some of the important and useful features of the Stylus Common UI?
• What are the key ways in which the Stylus Common UI is different from the default UI?​

If you want to learn more about Stylus UI in the context of implementation, view the 45-minute recorded webinar on the Cadence support site.

iWatch is a real-time filesystem monitoring program. It is a tool for detecting any changes on your filesystem and reporting it to the system administrator immediately. It uses a simple configuration file in XML format and is based on inotify, a file change notification system in the Linux kernel.

cryptmount is a utility for creating and managing secure filing systems on GNU/Linux systems. After initial setup, it allows any user to mount or unmount filesystems on demand, solely by providing the decryption password, with any system devices needed to access the filing system being configured automatically. A wide variety of encryption schemes (provided by the kernel dm-crypt system and the libgcrypt library) can be used to protect both the filesystem and the access key. The protected filing systems can reside in either ordinary files or disk partitions. The package also supports encrypted swap partitions, and automatic configuration on system boot-up.
