On the first two chapters of this Tutorial we started with a simple LFSR module and added a test bench. Then, on chapters three and four we upgraded our module with some features and learned to export the test bench data to files.

Pseudo random generator tutorial in VHDL (Part 2/3)
In the first part of this tutorialwe started with a simple implementation of an LFSR block (Chapter 1) and its test bench (Chapter 2). Let’s make our code look a bit more professional.

Pseudo random generator tutorial in VHDL (Part 1/3)
In this tutorial we will see how to design a VHDL block. We will start with a very simple block and we will gradually add features to it. We will also simulate it and test its output with Matlab. Over the process we will see:

Striving for one code base in accelerated testbenches
Teams buy HDL simulation for best bang for the buck. Teams buy hardware emulation for the speed. We’ve talked previously about SCE-MI transactors as a standardized vehicle to connect the two approaches to get the benefits of both in an accelerated testbench – what else should be accounted for?… Read More
Optimization and verification wins in IoT designs
Designers tend to put tons of energy into pre-silicon verification of SoCs, with millions of dollars on the line if a piece of silicon fails due to a design flaw. Are programmable logic designers, particularly those working with an SoC such as the Xilinx Zynq, flirting with danger by not putting enough effort into verification?… Read More
SoC QoS gets help from machine learning
Several companies have attacked the QoS problem in SoC design, and what is emerging from that conversation is the best approach may be several approaches combined in a hybrid QoS solution. At the recent Linley Group Mobile Conference, NetSpeed Systems outlined just such a solution with an unexpected plot twist in synthesis.
The… Read More
The Emerging Importance of Parallel SPICE
SPICE simulation is the workhorse tool for custom circuit timing validation and electrical analysis. As the complexity of blocks and macros has increased in advanced process nodes — especially with post-layout extraction parasitic elements annotated to the circuit netlist — the model size and simulation throughput… Read More
From Simulation to Emulation: 3 Steps to a Portable SystemVerilog/UVM Testbench
If your team is building large, complex designs that require millions of clock cycles to fully verify, you need both simulation and emulation.
Using emulation with simulation accelerates performance for dramatically reduced run times.… Read More
Webinar alert – Taking UVM to the FPGA bank
UVM has become a preferred environment for functional verification. Fundamentally, it is a host based software simulation. Is there a way to capture the benefits of UVM with hardware acceleration on an FPGA-based prototyping system? In an upcoming webinar, Doulos CTO John Aynsley answers this with a resounding yes.… Read More
Webinar: A Tool for Process and Device Evaluation
Not only are foundries continuing to introduce processes at new advanced nodes, they are frequently updating or adding processes at existing nodes. There are many examples that illustrate this well. TSMC now has 16FF, 16FF+ and now 16FFC. They are also announcing 10nm and 7nm processes. In addition, they are going back to older… Read More
