Steps to install and run on UBUNTU:
1) sudo apt-get install git
2) git clone https://github.com/kunalg123/vsdflow.git
3) cd vsdflow
4) chmod 777 opensource_eda_tool_install.sh
5) ./opensource_eda_tool_install.sh 
**NOTE for freshers : This has been tested on a fresh UBUNTU installtion
**NOTE for experienced UNIX users : It has lot of sudo apt-get and sudo remove commands, so you might want to review before running
6) ./vsdflow spi_slave_design_details.csv
7) ./vsdflow picorv32_design_details.csv

Steps to install and run on CENTOS:
First login as root using below command (IMPORTANT)
su -
Then follow below steps

2) git clone https://github.com/kunalg123/vsdflow.git
3) cd vsdflow
4) chmod 777 opensource_eda_tool_install_centos.sh
5) sudo ./opensource_eda_tool_install_centos.sh 
**NOTE for freshers : This has been tested on a fresh CENTOS 7 installtion
**NOTE for experienced UNIX users : It has lot of sudo yum commands, so you might want to review before running
6) ./vsdflow spi_slave_design_details.csv
7) ./vsdflow picorv32_design_details.csv

'vsdflow' is also the best utility ever written for learning EDA based TCL scripting...Very hard to find a tool, with its detailed explanation in form of videos. 'vsdflow' is explained (in detail) in below 2 TCL scripting courses, so you might want to have a look:

TCL scripting part 1:
https://www.udemy.com/vsd-tcl-programming-from-novice-to-expert/

TCL scripting part 2:
https://www.udemy.com/vsd-tcl-programming-from-novice-to-expert-part-2/

This course has gone to a level, where I have heard managers in VLSI industries asking their team to learn TCL only through this course and 'vsdflow'.

VSDFLOW  is  an  automated  solution  to  programmers, hobbyists and small scale semiconductor technology entrepreneurs who can craft their ideas in RTL language, and convert the design to hardware using VSD (RTL-to-GDS) FLOW. VSDFLOW  is  completely  build  using OPHW tools, where the user gives input RTL in verilog. From here on the VSDFLOW takes control, RTL is synthesized (using Yosys).

The synthesized netlist is given to PNR tool (Qflow) and finally Sign-off is done with STA tool (using Opentimer). The output of the flow is GDSII layout and performance & area metrics of your design. VSDFLOW also provide hooks at all stages for users working at different levels of design flow. It is tested for 30k instance count design like ARM Cortex-M0, RISC-V picorv32, and can be further tested for multi-million instance count using hierarchical or glue logic.

Some background about VLSI backend is needed for to understand 'vsdflow' operations, so here are 3 important courses: (check with your interviewer and they might recommend these courses):

There you go...Write your first TCL script, learn it from basics to advanced to expert level, apply it from EDA perspective, and you are good to go for your job or interviews....

All the best and happy learning
