Infineon-Summer-School

This is a project written in verilog for the first week of Infineon-Summer-School. The purpose was to implement a Universal Asynchronous Receiver-Transmitter. You can check the documentation on which this project is based here. For verifing the implementation I used Cadence XCelium.

This is how the first week looked like:

• Prologue

  • visited a couple of the company's labs
  • listened to a presenation about the stages of developing a product

• First day (beginner friendly)

  • learned to use X2GO (how to create a session, how to add shared folders)
  • customized my workspace to be nicer
  • rediscovered basic linux commands (cd, pwd, ls with all the nice flags and others)
  • helped two colleagues understand how to work their way in the X2GO client and linux
  • revisioned base CID concepts
  • learned to use gedit as text editor and Cadence XCelium as simulator
  • started writing the baudrate generator to lower the frequency of the systems clock

• Second day

  • wrote a testbench for the baudrate generator to check all the 4 possible rates
  • kept the .v's organized by using separated folders for register-transfer level designs and the testbenches
  • debugged the code of some fellow participants (most of them encountered troubles with creating the option to have 4 possible rates)
  • started writing the first in first out buffer to create a storage structure that follows the fifo rule

• Third day

  • improved some lines of code in the control part of the fifo buffer
  • wrote a testbench for the fifo buffer to check the empty and full flags and if it respects the fifo rule
  • designed on paper the uart_tx with its states
  • started writing the uart_tx which is a finite state machine at base
  • helped a couple of colleagues understand the non-blocking attribution and how to move from one state to another
  • revisioned CID automated concepts

• Fourth day (pray day)

  • finished the uart_tx without writing a testbench for it and started praying
  • wrote the main file of the project uart_transmitter which linked all the other files and continued the prayers
  • wrote the nicest testbench that I could, to see if the uart_transmitter actually works
  • simulated the testbench a couple of times and kept on modifying the uart_transmitter until it was showing the normal waveform
  • encountered some problems going from STOP to IDLE so kept on modifying until the waveform actually worked
  • reviewed the entire code, and added comments for a better understanding

  Future repeats itself
