A Simple Approach to Project Task Management

Project Task Management

While developing new code, you likely have often had a quick glimpse of a problem or situation you would like your code to handle but had no time to deal with that idea right away. Perhaps you kept notes on a piece of paper or even filed formal tickets in a bug tracker, but there is a better way - maintaining notes directly in the source code.

Starting with Riviera-PRO release 2012.06, anywhere in a file managed by Riviera-PRO, you can now add a comment which starts with a predefined tag, leaving a note to yourself (or other project team members): Read More

Fast Track to UVM - Training Seminar


Let's be honest - typical, busy hardware designers treat Universal Verification Methodology (UVM) like black magic. Perhaps you’ve learned design subset of SystemVerilog, but have not found the time to play with the advanced verification features required to write with UVM.

For this busy group of SystemVerilog users, Aldec has prepared a new Seminar series, Fast Track to UVM, Read More

Bartender's Corner: Managing a Cocktail of SPICE, Verilog-AMS, Verilog/SystemVerilog, and VHDL

Creating and verifying mixed-signal (A/MS) integrated circuits is a challenge. Spice-based simulation provides the accuracy needed for the analog design, but is too slow to handle the digital part. Event-driven digital simulation provides the necessary speed to simulate the digital portions, but fails when dealing with the analog parts.

As mixed-signal designs continue to growing in complexity due to functionality and capability requirements, design teams also face pressure to shorten time to market and reduce re-spins. This rapidly changing environment dictates the need for a new A/MS solution Read More

Using Aldec Riviera-PRO to Verify RTL Auto-Generated by Vivado™ HLS

Vivado™ HLS (high-level synthesis) is a new addition to Xilinx tool suite based on extensive evaluation of commercial system-level (ESL) design tools followed by the acquisition of AutoESL Design Technologies, Inc. back in 2010. It enables an alternative approach to the traditional Xilinx FPGA design methodology by enabling algorithmic (rather than typical hardware) development environment. Instead of manually creating a register-transfer-level (RTL) implementation, designers can cut development time by orders of magnitude by representing their algorithms at a higher level of abstraction (C, C++, or SystemC) and verifying reference system behavior at the same level of abstraction.

DO-254 Practitioner's Course: DO-254 Demystified

"The breaking down of the dreaded DO-254 document into manageable sections of information was quite beneficial for me. The instructors were very knowledgeable about the subject and did not hesitate to make the students feel right at home when discussing DO-254."

-Dexter Wimberly, Design Verification Engineer at L3 Communications

"Very good practical experience and helpful hints."

-William Schnepp, Engineering Specialist at Williams International

"The aspects of the course that I found beneficial include the material for FFPA, clarification on level of details that needs to go in the requirements, verification approaches and how the FAA works."

-Santhi Ayyadevar, Verification Lead at eInfochips.

In 3 days, attendees such as airframer and avionics suppliers, Embraer, Honeywell, Parker Aerospace, Turkish Aerospace, Goodrich and SAAB, learned how to apply DO-254 to FPGAs - enabling them to work independently in this area.

"What's New" presentation: Riviera-PRO 2012.06 What's New

ALINT™ 2012.01

Stay tuned for the next release of ALINT product scheduled to arrive this fall (October’2012). Here is a heads up on some of the new features coming:

  • New rules in ALDEC_VLOG and ALDEC_VHDL basic rule plug-ins, helping to reduce long routing delays. The new rules will be addressing issues associated with fanout, logic levels, and output registers.
  • Tighter integration with Riviera-PRO verification platform. The new version of ALINT is going to be integrated with the project tasks management, a new functionality available with the latest version of Riviera-PRO, 2012.06. Project teams that develop their designs using Aldec tools will be able to take automated code reviews to the next level by quickly creating project tasks based on violations detected during a linting session. For example, a person performing code review or audit would be able to quickly create and delegate action items to the other project team members.
  • Revised exclusions management mechanism for more granular management of project-specific waivers. The updated mechanism will provide means for violation-accurate exclusion management, enabling ALINT users to disable any particular violation based on specific attributes such as location in source and contents of the violation itself.

Aldec Quick Tips

Active-HDL's Connect To Simulator feature allows AWC files from other simulations to be connected to running simulation. It automatically traces all relevant signals and links the AWC file to the current simulation database. This feature is available in waveform menu.

Active-HDL allows designers to automatically generate macros/scripts for compilation and simulation. Users can set the the order of compilation from Design Compilation Order option located in Design menu - then go to Design menu and click on Generate Macro.

Riviera-PRO offers a Block | Create Template option (available from the context menu of the HDL Editor) to enable quick creation of custom templates based on a current code selection. The custom template wizard automatically extracts “special fields”, enabling Tab and Shift+Tab hotkey navigation between those fields later, when a template is used. Templates can be shared across organization to facilitate code editing and reuse, see manual for more.

Riviera-PRO's file-level settings enable customizing compilation properties for each individual design file in GUI mode operation (the batch mode users can simply specify multiple compilation commands to achieve the same). The option is available from the right-click menu of Design Manager and comes handy when a design includes files compliant with different standards of the same language, VHDL’2002 and VHDL’2008 for example.
