Description

This project is a collection of small designs involved with clock boundaries.
The clock_switch designs are based on an eetimes article.
The bc_fifo_basic design is based on ideas from generic_fifo_dc_gray.

Features

- debouncer: debounce a mechanical switch.
- clock_switch2_basic: select 1 of 2 clocks, no glitches.
- clock_switch3_basic: select 1 of 3 clocks, no glitches.
- clock_switch4_basic: select 1 of 4 clocks, no glitches.
- clock_switch8_basic: select 1 of 8 clocks, no glitches.
- oc_fifo_basic: a one-clock fifo
- bc_fifo_basic: a boundary-crossing fifo
- clock_detect: a clock-active detector
- arbiter: a simple parameterized round-robin arbiter
- random_ff: a ff simulation model for async boundaries

Status

- None of these designs have been verified in silicon.
