This is Mur 
@freemo
Well I know basic electrical concepts like capacitance, inductance, three phase circuits, transformers, etc
🇳🇱
@mur2501 KVL and KCL?
@freemo
ofcourse KVL and KCL, node analysis, Thevenin and Norton's transformation, etc
@mur2501 Oh I'd say if you know proper nodal analysis then your more than just a beginner then. So you are comfortable with AC circuits as well?
@freemo
Well Indian education is very deep in theory while practice is scarce.
So I know theoretical stuffs but I don't have any practical experience with electronics. 
@mur2501 In that case it isnt tools or software or even books you need, its a soldering iron and a sack full of components :) Maybe a oscilloscope to go with it.
@freemo
Not really something for which I would get money from my parents for 
For now I can do with circuit simulators 
@mur2501 circuit simulators still wont get you past pure theory though.. the real world cant be simulated ...
@freemo
yeah but indishland in lockdown makes real world inaccessible 
Else I would have had practical exposure for the experiments in college 
@mur2501 fair, well hopefully that will change soon.

@zleap @freemo @mur2501 Nope. So, Arm is to RISCV like amd is to Intel (in a way, not in everything). Meaning, Arm has their own ISA (instruction set architecture) of which the most famous is probably the A64 (arm64). Meanwhile, RISC-V aims to be a license free ISA so companies don't have to pay for example.
Another important concept here that is often misunderstood is the difference between an ISA and it's underlying implementation. Meaning, I could have an operation defined as `ADD x y` in Armv8-A (64bit arm ISA) but there are many ways that this function could be implemented in actual hardware. Typically, manufacturers like ST Microelectronics will license both Arm's ISA as well as their internal designs to make a real hardware chip that has implemented the design. However, manufacturer are often free to deviate in their implementations from the "official" Arm one. As long as it still implements all the ISA it can be called "an Arm-based chip/ microcontroller".
In general, if this is the part of electronics you're interested in. Just learn vhdl/verilog.
@zleap @freemo @mur2501 forgot to mention about the acronym. It's both Advanced RISC Machines and Acorn RISC Machine, Arm was originally born from Acorn Computers, nearly died as a company and then reborn again thanks to Apple in order to bring the Apple Newton to life which used the ARM 610 processor.
@mur2501 Well I cant help too much in semiconductor design as I never designed a chip itself. Though I do understand some domains that you need to know to design a chip and are closely related... like digital logic, or even just general electronic circuit analysis.
Where are yo in your journey right now, do you know anything in the field, even just basic stuff?
