– 没有你的支持,这是不可能的

our company to move from LMS (Learning Management System) to EMS (EDA Management System), and finally we envision, very soon to be in DMS (Design Management System).Talking about ‘vsdflow’, it’s the main theme of this paper, and if I had to describe it in few lines, it’s a ‘plug and play (PnP)’ EDA management system, built for chip designers to implement their ideas and convert to GDSII.

Committed in 2011, delivered in 2018

the flowchart is what you need to understand just to be an expert in the field of VLSI and semiconductors. Every topic shown in above image is a field, and every topic has a beautiful physics behind it, which when blended with tools in a video course, becomes a master-piece

Facts – About below open-source EDA tool

Why “integrated”? Because at lower nodes, you have to integrate other parts of the flow. Sign-off (you can see power and timing buttons below), clock tree synthesis (you can see synthesis button) must be integrated, so we have a fully integrated PnR flow that we built from day one.

VSDSYNTH – An unique UI for synthesis and pre-layout timing

online VLSI courses using open-source tools, VSDSYNTH, our new product (currently in beta testing) is unique UI that will take in inputs in form of RTL netlist and read standard SDC format constraints. The UI will generate synthesized netlist and pre-layout timing reports, hereby giving you first hand information on the quality of your RTL design

From RISC-V architecture to Layout – Coming Soon

A high-level program, like swap.c as shown below is first converted to an assembly language program (RISC-V in below example) using compiler. This assembly language is converted to binary machine language program using an assembler. This level of abstraction of your application using high-level programming languages like C, C++, Java or Visual Basic, proves to be a great idea to improve design

read_sdc – clock constraints

read_sdc is been considered as a very critical command in EDA world, as this is the command which defines your specifications, and if not written and interpreted correctly, can lead a huge delay in tapeout cycle.
