	Timeout target to auto-complete CSR transactions on a timeout.

Detailed Description

Modules

module csr_target_timeout::csr_target_timeout	(	clock	clk,
		input bit	reset_n,
		input t_csr_request	csr_request,
		output t_csr_response	csr_response,
		input bit	csr_timeout[16]
	)

This module provides a CSR target interface which never directly responds to a request, but which will complete a read or write if the request stays for a specified period of time.

This permits any transaction to be attempted by a CSR interface master, even if no target decodes the transaction. Such transactions will be handled by this module.

Parameters

[in]	clk	Clock for the CSR interface, possibly gated version of master CSR clock
[in]	reset_n	Active low reset
[in]	csr_request	Pipelined csr request interface input
[out]	csr_response	Pipelined csr request interface response
[in]	csr_timeout	Number of cycles to wait for until auto-acknowledging a request
