* Remove comment about the USRMCLK primitive being untested.Gary Wong2020-04-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Tested and verified working: the trivial configuration: module USRMCLK( USRMCLKI, USRMCLKTS ); input USRMCLKI, USRMCLKTS; endmodule module top( input clk ); reg[ 24:0 ] count = 0; always @( posedge clk ) begin count <= count + 1'b1; end USRMCLK mspi( .USRMCLKI( count[ 20 ] ), .USRMCLKTS( count[ 24 ] ) ); endmodule produces the expected output (toggling at high frequency, toggling tri-state at lower frequency) on an LFE5U-85 when fed with an appropriate clock. See https://bayimg.com/AAnNKAAGO for an example. The top (magenta) trace is the MCLK line.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We raise a C++ exception to abort the rest of the execution of the function. At the same time we standardize on using a throw runtime error as the method to avoid warning when not returning values. (some places used this throw and some other used std::terminate) Fixes #403 Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
