Usually people just slice the bit you want off a counter. To select the bit using a software register, just use the software register as the select for a mux. Or use the software register as a bit mask and AND it with the counter, then use the output of a relational == 0 as your divided counter. O

[casper] Simple clk divider

2013-11-13 Thread Ross Williamson
Hi All, I suspect this is really simple but I just cannot get this to work in simulink. I would like to divide the sys_clk by a factor set by a software register. To do this in VHDL is very simple - You setup a counter and invert the output when it reaches half of the required clk divide - the c
