# As everyone will have access to all designs, try to make it easy for someone new to your design to know what
# it does and how to operate it. This info will be automatically collected and used to make a datasheet for the chip.

  title:        "TT05 Analog Testmacro (Ringo, DAC)"
  language:     "Analog"
  description:  "For future analog enablement of TinyTapeout we designed a few simple analog blocks for testing the flow. The first block is a ca. 500kHz ring oscillator outputting a square-wave signal. The second block is a 3bit R-2R DAC outputting a programmable dc voltage. Both analog output signals can be gated or shorted using integrated transmission gates. To add a further level of madness, we have placed and routed this analog macro using an experimental automatic analog PnR tool, currently under development by the authors."

# Longer description of how the project works. You can use standard markdown format.
  how_it_works: |
      A ring oscillator (ca. 500kHz) produces a square-wave signal available at UA[0].
      A 3-bit R-2R DAC produces a dc voltage availabel at UA[1].

# Instructions on how someone could test your project, include things like what buttons do what and how to set the clock if needed
  how_to_test:  |
      Enable the respective blocks, and enable the transmission gates to connect the block outputs to UA[0] and UA[1], respectively. The DAC voltage can be changed by setting the digital inputs accordingly.

# A description of what the inputs do (e.g. red button, SPI CLK, SPI MOSI, etc).
  inputs:               
    - IN[2:0]: Digital input for DAC
    - IN[3]: Enable TG for DAC output to UA[1]
    - IN[4]: Not used
    - IN[5]: Enable TG for ringo output to UA[0]
    - IN[6]: Enable ringo 
    - IN[7]: Short UA[0] and UA[1] for testing
# A description of what the outputs do (e.g. status LED, SPI MISO, etc)
  outputs:
    - UA[0]: Ringo output (if TG enabled)
    - UA[1]: DAC output (if TG enabled
# A description of what the bidirectional I/O pins do (e.g. I2C SDA, I2C SCL, etc)
