-- Module: Poc.arith_counter_free
--
-- Authors: Thomas B. Preusser
--
-- Description:
-- ------------
-- Implements a free-running counter that generates a strobe signal
-- every DIVIDER-th cycle the increment input was asserted.
-- There is deliberately no output or specification of the counter
-- value so as to allow an implementation to optimize as much as
-- possible.
-- The implementation guarantees a strobe output directly from a
-- register. It is asserted exactly for one clock after DIVIDER cycles
-- of an asserted increment input have been observed.

Dataset Card for AI-HDLCoder
Dataset Description
The GitHub Code dataset consists of 100M code files from GitHub in VHDL programming language with extensions totaling in 1.94 GB of data. The dataset was created from the public GitHub dataset on Google BiqQuery at Anhalt University of Applied Sciences.
Considerations for Using the Data
The dataset is created for research purposes and consists of source code from a wide range of repositories. As such they can potentially include harmful or biased code as well as sensitive information like passwords or usernames.
