#!/usr/bin/python
# This program creates a VHDL entity that sorts the taps of the delay line
# by increasing delays, according to the Xilinx static timing model.
#
# 1. Create a design in ISE with the delay line only, for the targeted FPGA.
# If you run out of I/Os, connect some dummy logic to the taps to prevent
# optimizations. Use this Verilog source for example:
#module top(
# input clk_i,
# input reset_i,
# input signal_i,
# output xtap
#);
#
#wire [124*4-1:0] taps;
#
#tdc_delayline #(
# .g_WIDTH(124)
#) dl (
# .clk_i(clk_i),
# .reset_i(reset_i),
# .signal_i(signal_i),
# .taps_o(taps)
#);
#
#assign xtap = |taps;
#
#endmodule
# 2. Apply this UCF constraint:
# NET "signal_i" OFFSET=IN 20 ns BEFORE "clk_i";
# 3. Implement the design.
# 4. Generate the XML timing report (.twx): trce -v 1000 top.ncd
# 5. Process it with this program.
