      Theodor-Adrian Stana authored
      - substitute FIFO for ring buffer
      - change pulse repetition duty cycle to 1/500
      - renamed some files to make "generic" naming
      - release: add I2C simulation capabilities
      - conv_pulse_gen: change testbench.vhd for simulating 1/500 duty cycle
      - update project file with new files

      Pre-version 2.0 commit · 64f1a255
      Theodor-Adrian Stana authored
      - added pulse time tagging core (pulse_timetag.vhd)
      - added FIFO via the conv_regs.wb file
      - to make the FIFO read work properly, I needed to change the
      wb_i2c_bridge component (general-cores submodule)
      - updated top-level to connect the FIFO to conv_regs component
      - moved the pulse generator glitch filter to outside the pulse
      - changed the conv_pulse_gen block to be able to properly reject
      pulses up to only 1/5 duty cycle, not more (I realized by simulation
      that when the glitch filter was enabled, it needed one extra cycle,
      thus the duty cycle of the pulse was not 1/5, but 1/5 + one clock cycle)
      - updated synthesis files for the Release project to add the new files,
      and the regtest and pulsetest due to the I2C bridge changes
      Simulation files:
      - conv_pulse_gen: changes for the aforementioned change test
      - added pulse_timetag sim files
      - added release top-level simulation, which at the moment does
      not contain a lot of stuff (only pulse rep test), but can be used as a
      starter to verify the design works appropriately
      - updated memory map with cute wbgen-ized memory map
      - added time-tagging core information
      - updated the Getting Around the Code section
      - added and updated figures
