Hi All, We have clock generation block in one module. The actual code in VHDL is like this VHDL ::: Clk_1M_s_p : process begin Clk_1M_s <= '0'; wait for 0.5 us ; Clk_1M_s <= '1'; wait for 0.5 us ; end process Clk_1M_s_p; VERILOG ::: timescale 1fs/1fs always b...
在VHDL中,可以用语句(clock’ event and clock=’0’) 表示检测clock下降沿。ENTITY EXAMPLE ISPORT(A,B,C: IN
I've been reading other posts about modeling clock in vhdl, now: 1. i see that delays are just for simulations, not for physical implementations 2. same for falling and rising edge triggers in same process are this points correct? i've tried too, to make a frecuency multiplier (specifi...

The process you have written will generate only a enable flipflop. Please be specific and more clear about your problem so that people can give you
The article discusses a method of building a universal, parameterized clock management module for the process of functional simulation. The solution was designed for various families of FPGA circuits and popular VHDL compilers. The algorithm for automatic module configuration for given parameters of ...
