Hello, I was coding clock divider in VHDL and was told that it's not a good idea to do so. How do I use the DE2's onboard clock divider?
MachXO2 Clock Divider 11.1. CLKDIVC Primitive Definition The CLKDIVC primitive can be instantiated in the source code of a design as defined in this section. Figure 11.2, Table 11.1, and Table 11.2 show the CLKDIVC definitions. CLKDIVC CLKI RST ALI GNWD CDIV1 CDIVX Figure 11.2. CLK...

VHDL-AMS also allows us to trigger a digital event based on changes in analog quantities using the ‘above attribute, which we described in Section 6.3. Recall that this attribute Q'above(E) yields a Boolean signal, and that the transition of the quantity Q above or below the value of th...
In particular, the 21 264 Floating Point Unit has a controller that can freeze the clock to its components, such as the adder, multiplier, divider, etc., according to the instructions to be executed, so that the idle components do not waste power. The PowerPC 603 processor [14] has ...

These improvements are such as describing the PLL in synthesizable VHDL code and improved phase error measurement. 2. DESIGN OVERVIEW Figure 2 shows the block structure for the all-digital PLL. The phase detector is controlling the counter, which is in this configuration is clocked by "clk_out...
举个例子,VHDL编译的时候,文件的先后顺序要有非常严格的规定,但verilog就不是这样子,只要在里面有,就没有问题。 那在coding的时候,无非就是两个大的方向,要么是靠平台的,要么是sequential。还有一些IP,比如说,像一些SRAM,一开始的时候,前期的时候呢,也不知道是要到哪个foundry,就写一些module。那最后就要注意了,...
I'm currently designning a VHDL code for traffic light (two processes) coding style and i bump to this error regarding clock timing: Error (10818): Can't infer register for "state.s0" at traffic.vhd(44) because it does not hold its value outside the clock edge Error (10818): Can...
