在英特尔官网上有给出该错误的解决方案,即在工程的.qsf文件中添加 set_global_assignment -name VERILOG_NON_CONSTANT_LOOP_LIMIT 300。 此时循环次数上限修改为 300,实测最大循环上限为 5000,这是很多Verilog教材中没有提到的。 方法二:当然就是换一个循环语句了,用for之类的循环不香么。 (2)for循环 格式: f...

SystemVerilog added the ability to put the genvar inside the for loop. Verilog-2005 made the generate/endgenerate keywords optional. The compiler should be able to tell from the context whether the for-loop is a generate-for or a procedural-for. I would try removing them and seeing if ...

Using SystemVerilog for FPGA Design - 中文 FPGA设计中使用的SystemVerilogSystemVerilog中包含了比用于FPGA设计的Verilog语言增强了的许多功能，。从FPGA供应商和EDA工具供应商的综合工具使SystemVerilog的设计，以比在Verilog更容易理解的风格和较高的抽象层次的描述，加快编码过程和缓和重用。本文着眼于如何综合的System...

You can use a generate for loop instead of foreach. genvar bit_number; generate for(bit_number=0;nit_number<?;bit_number=bit_number\+1) begin : if ( selector [ bit_number ] == 1'b1 ) assign destination [ bit_number ] = source_1 ; else assign destination [ bit_number ] = ...
found a better solution for Quartus Std., use generate for instead of simple for loop. genvar i; generate for (i = 0; i < NUM_BYTES; i++) begin : gen_be always@(posedge clk) if(we & be[i]) ram[waddr][i] <= wdata[i*BYTE_WIDTH +: BYTE_WIDTH]; e...
