verilog 代码://---假设 reg [n-1] gray,binary; integer i; for(i=0;i<=n-1;i=i+1) binary[i]= ^(gray>>i)//gray移位后,自身按位异或^(gray>>i)//第一次看到这样的用法,特意查了下verilog语法 Verilog 的位运算语法: 位逻辑运算符 在Verilog语言中有7种位逻辑运算符: 1 ~ (非) 2 & ...
Referring to previous posts I am trying to implement spislave on XC3S200 FPGA using verilog. I have made the following code. In behavioral simulation it is working properly. But in Post Place and Route simulation model, count and shift_reg are behaving in some diff way. Like when count i...

We can write a configuration declaration for the design as shown in Figure 17-15. The block configuration starting with “for bank_array” selects the memory array generated by the outer generate statement labelled bank_array. Each bank is configured identically, using the inner block ...
OpenCL C, C/C++, and HDLs (e.g., Verilog or VHDL) are all supported for a kernel development. In this paper, we design and implement the two kNN kernels in C++ and then convert them to a low level design through Xilinx HLS, which are then executed under the OpenCL framework. The...
The readMemHesH function has the same name and the same parameters as its declaration on the Verilog side. The DPI_LINK_DECL macro is used to add extern "C" before the function declaration if it is compiled with the C++ compiler. Thus, it is exported in the C format, required for the...
3. In modelsim's workspace window library TAB, I select the top-level entity to simulate 4. after simulation starting, I try to observe content of onchip_memory (note:my 64KB onchip_memory has been devided into 128 M4K modules, the following show you the first M4K ...
in which case it specifies the default implementation style for all inferred memory blocks in the immediate hierarchy. You can also set the attribute on a specific signal (VHDL) or variable (Verilog HDL) declaration, in which case it specifies the preferred implementation style for that ...
4. Using a text editor, write the component declaration for the module in the top-level design file. 5. Verilog Synthesis Attributes are already incorporated in the LPM modules unlike the VHDL modules. 6. Open the module file that you generated with Module/IP Manager (ram_dp_1024x8.v)....
