Blog Review: May 9
By Jesse Allen - 09 May, 2018 - Comments: 0

Mentor's Doug Amos explains the differences (and similarities) between verification and validation, why switching between engines needs to be simpler, and why the limits of verification are driving a growth in validation importance. Synopsys' Melissa Kirschner provides a primer on 5G and the five technologies that will need to work in tandem to bring the promised high speeds and low latency.... » read more

Arm's Greg Yeric looks towards the future of 3D ICs with a dive into transistor-level 3D, including the different proposed methods of stacking transistors, power/performance benefits, and challenges such as parasitic resistance. Mentor's Kurt Takara, Chris Kwok, Dominic Lucido, and Joe Hupcey III explain how a custom synchronizer methodology can help avoid CDC mistakes and errors in FPGA des... » read more

Partitioning Becomes More Difficult
By Ann Mutschler - 30 Apr, 2018 - Comments: 0

The divide-and-conquer approach that has been the backbone of verification for decades is becoming more difficult at advanced nodes. There are more interactions from different blocks and features, more power domains, more physical effects to track, and far more complex design rules to follow. This helps explain why the number of tools required on each design—simulation, prototyping, em... » read more

Inside UVM, Take Three
By Vatsal Choksi - 26 Apr, 2018 - Comments: 0

The reason why UVM came up with such phases is because synchronization among all design-testbench was necessary. Using Verilog and VHDL, verification engineers did not have facilities such as clocking block or run phases. Now, it is very important that the time at which test vectors applied from test-bench reaches the Design Under Test(DUT) at the same time. If timing for different signals vari... » read more

By Aldec - 25 Apr, 2018 - Comments: 0

This white paper explains Reset-related ASIC and FPGA design issues as well as outlines commonly-used design techniques leading to safe reset implementations. It goes on to explain about Reset Domain Crossing effects and methods to mitigate their influence on design. LINT tools provide valuable help for designers in Resets and Reset Domain Crossings verification. To download this paper, clic... » read more

The Week In Review: Design
By Jesse Allen - 13 Apr, 2018 - Comments: 0

Tools & IP Cadence unveiled its latest DSP for embedded vision and AI, Tensilica Vision Q6 DSP. The DSP is built on a 13-stage processor pipeline and new system architecture designed for use with large local memories, and achieves 1.5GHz peak frequency and 1GHz typical frequency at 16nm. Compared to its predecessor, it offers 1.5X greater vision and AI performance than its predecessor and ... » read more

Simplifying SystemVerilog Functional Coverage
By Henry Chan - 22 Mar, 2018 - Comments: 0

Let’s say you have a block you need to verify. How do you know that the stimulus you are about to use is exhaustive enough and that you have covered the necessary scenarios/situations to prove it is working correctly? This is where functional coverage comes in. SystemVerilog’s functional coverage constructs allow you to quantify the completeness of your stimulus by recording the values that... » read more

Merging Verification With Validation
By Brian Bailey - 22 Mar, 2018 - Comments: 3

Verification and validation are two important steps in the creations of electronic systems and over time their roles, but how they play together is changing. In fact, today we are seeing a major opportunity for rethinking this aspect of the flow, which could mean the end of them as separate tasks for many of the chips being created. As with many things in this industry, however, squeezing it... » read more

DO-254: Increasing Verification Coverage By Test
By Aldec - 21 Mar, 2018 - Comments: 0

Verification coverage by test is essential to satisfying both the objectives of DO-254 and interpretation in FAA Oder 8110.105. However, verification of requirements by test during final board testing is challenging and time-consuming in most cases. This white paper explains the reasons behind these challenges and provides recommendations for how to overcome them. The recommendations center ... » read more
