Hey There – Think about it!!! Last week, we shared our idea and vision of “How to define the width and height of core and […]
Hey There – Think about it!!! Today’s version of open-source EDA tools, work very well for hierarchical designs sub-25k instance count. For hierarchical designs ~500k […]
With learning being online, SHAKTI core and ‘vsdflow’ being opensource, this is first-time in the history of VLSI design & EDA (thanks to RISC-V ecosystem and Shakti Team at IITM lead by Prof. Kamakoti), a chip will ever be taped-out using all open source flow, which will cater to almost 80% Indian Semiconductor Market.
It wasn’t that bigger deal for Intel because they thought, at the time, it will be 250,000 chips will be sold for 5 years, which isn’t that many. But they were wrong. It was a 100Million computers were sold. And suddenly 8086 from being an emergency back-up was an over-night success and had a very bright future, because it was binary compatible of PC software, and so had great opportunity
Isn’t that an inspiring story?
In last 50 years, there are 3 lessons that we can draw. First – software advances can inspire architecture innovations. Second – when we raise the hardware/software interface, it creates opportunities for architecture innovation. Third – in our field, the way we settle these debates, isn’t by just arguing in a bar, rather people spent/invest billions of dollars to investigate their ideas and marketplace settles these debates
Hi “Pictures speak it all” Finally, we all did it – VSDOpen – first ever online VLSI conference. Very close to a real one – […]
“Design at $0” is an initiative driven by our team at VSD.Working in open environment is much easier process as all the resources are openly available, but here arise the loophole.
Transaction-Level Verilog (TL-Verilog) is an emerging extension to SystemVerilog that supports transaction-level design methodology. In transaction-level design, a transaction is an entity that moves through a microarchitecture. It is operated upon and steered through the machinery by flow components such as pipelines, arbiters, and queues. A transaction might be a machine instruction, a flit of a packet, or a memory read/write. The flow of a transaction can be established independently from the logic that operates on the transaction. We present a preliminary library of TL-Verilog flow components that can be quickly stitched together to establish a complete microarchitecture. We show how transaction logic, like packet decoding, can be added within this flow.
This paper introduces TL-V erilog and W ARP-V and then describes the formal verification of WARP-V using riscv-formal, a formal verification framework for RISC-V. Timing-abstraction and transaction-level design are showing significant benefits for hardware modeling, but this is the first demonstration of their benefits for verification modeling. As evidence of these benefits, the verification of all RISC-V configurations of WARP-V is accomplished in a single page of code.
Steve Hoover is the founder of Redwood EDA. Steve holds a BS in electrical engineering from Rensselaer Polytechnic Institute and an MS in computer science from the University of Illinois. He has designed numerous components for high-performance server CPUs and network architectures for DEC, Compaq, and Intel. Students will learn Transaction-Level Verilog modelingtechniques to generate Verilog models in half the time using the makerchip.comfree online IDE. A new open-source RISC-V CPU development effort will be introduced that showcases flexible IP design practices.
