Verilog File Operations Verilog Command Line Input 11. Miscellaneous Verilog Namespace Value Change Dump (VCD) Verilog VCD Dump A set of Verilog statements are usually executed sequentially in a simulation. These statements are placed inside aproceduralblock. There are mainly two types ofproceduralblo...
Verilog中的过程性语句结构主要有以下两种: intial语句; always语句; 在数字设计或者验证平台的搭建过程中,一个模块可以包含任意多个initial语句和always语句,并且这些语句在同一个模块中是并行执行的(需要注意避免竞争情况出现,特别是多个进程对同一个信号的控制)。 两者的主要区别如下表所示: 注意:经常在使用initial时...
Error (10170): Verilog HDL syntax error at dsb.v(10) near text: " "; expecting ";". Check for and fix any syntax errors that appear immediately before or at the specified keyword. Code before the initial block is:module dsb (clk_c, plc_lsb, plc_usb, dsb);input clk_c;output pl...
I am using a Verilog initial block to power-up certain reg's to high. My code looks something like this: reg a; reg[1:0] b; reg[2:0] c; initial begin a = 1'b0; b = 2'b11; c = 3'b111; end When I compile the design to run on ...
Multiple driver error for SystemVerilog initial value Question: Within my programming, a block of code, identified asalways_comb, has been implemented in the following manner: always_comb begin if ( x == 0 ) z = some_value ; else if ( y == 1 ) ...

In Verilog HDL, you can use an initial block to initialize the contents of an inferred memory. Quartus II integrated synthesis automatically converts the initial block into a .mif for the inferred RAM. Example 6–19 shows Verilog HDL code that infers a simple dual-port RAM block and co...
