Imperas in the News

4Q2021 release of Imperas simulator and reference models supports latest RISC-V Extensions for Bit Manipulation 1.0.0, Cryptographic (Scalar) 1.0.0, and Vector 1.0 plus Privilege Specification 1.12 as RISC-V Board formal approval is completed.

Imperas RISC-V Reference Models for latest ratified specifications

Oxford, UK – November 18th, 2021 – Imperas Software Ltd., the leader in RISC-V processor simulation and verification technology, today…

Software and hardware interdependencies complicate debug in embedded designs. New approaches are maturing to help reduce debug time.

Semiconductor Engineering

 

Debugging embedded designs is becoming increasingly difficult as the number of observed and possible interactions between hardware and software continue to grow, and as more features are crammed into chips, packages, and systems. But there also appear to be some advances on this front, involving a mix of techniques, including…

Technologies must evolve to keep up with changing demands, and emulation is no exception.

Semiconductor Engineering

 

Emulation is now the cornerstone of verification for advanced chip designs, but how emulation will evolve to meet future demands involving increasingly dense, complex, and heterogeneous architectures isn’t entirely clear.
EDA companies have been investing heavily in emulation, increasing capacity, boosting performance, and adding new…

Abstraction is the key to custom processor design and verification, but defining the right language and tool flow is a work in progress.

Semiconductor Engineering

 

High-quality RISC-V implementations are becoming more numerous, but it is the extensibility of the architecture that is driving a lot of design activity. The challenge is designing and implementing custom processors without having to re-implement them every time at the register transfer level (RTL…

The cloud cements its role in embedded hardware design.

Engineering and Technology

In the summer of 2018, professors John Hennessy and David Patterson declared a glorious future for custom hardware. The pair had picked up the Association for Computing Machinery’s Turing Award for 2017 for their roles in the development of the reduced instruction set computer (RISC) architectural style in the 1980s. 
Towards the end of their acceptance speech, Patterson pointed to the…

Imperas simulation technology and reference models now available within the TESSY environment for the automation of embedded software testing and regression management

Imperas Models available for Razorcat TESSY tools

Oxford, UK – October 18th, 2021 – Imperas Software Ltd., the leader in virtual platforms and high-performance software simulation, today announced Razorcat Developments, a leading provider of software testing tools for the embedded systems market, has integrated the Imperas fast…

Automatic mapping of software onto existing hardware, or using software to drive hardware design, are highly desired but very difficult.

Semiconductor Engineering

 

For the past 20 years, the industry has sought to deploy hardware/software co-design concepts. While it is making progress, software/hardware co-design appears to have a much brighter future. In order to understand the distinction between the two approaches, it is important to define some…

The open ISA of RISC-V means any SoC developer can now design a custom processor - moving the verification task from a few specialist suppliers to all SoC developers. This article looks at the industrial-grade verification and open methodology as used by the OpenHW verification working group.

RISC-V Processor Design Verification (DV)

One of the appealing things about open-source is that it invites…

New approaches emerge as demand for improved power and performance overwhelm design tools.

Semiconductor Engineering

 

The semiconductor ecosystem is at a turning point for how to best architect the CPU based on the explosion of data, the increased usage of AI, and the need for differentiation and customization in leading-edge applications.

In the past, much of this would have been accomplished by moving to the next process node. But with the benefits from…
