随机的对象不只是一个数据,而是有联系的变量集。通常这些变量被封装在一个数据类中,同时需要在类中声明数据之间的约束关系。因此约束之后要产生随机数据需一个“求解器”,即在满足数据本身和数据之间约束关系时的随机数值解; 约束不但可以指定数据的取值范围,还可以指定各个数值的随机权重分布。 需要随机什么? 器件配...
如果条件为false,则循环将在此处结束。do while 因此,两者之间的区别在于,循环至少执行一次语句集。do while Syntax while(<condition>)begin// Multiple statementsenddobegin// Multiple statementsendwhile(<condition>); Example #1 - while loop moduletb;initialbeginintcnt =0;while(cnt <5)begin$display("...
在verilog文件中定义的宏,但错误显示在modelsim中未定义的宏 我已经在一个verilog文件中定义了所有verilog文件的宏,比如FabScalarParam.v,我首先在system.do文件中编译FabScalarParam.v,然后编译其他verilog文件但是当我运行"do system.do“来编译设计时,它会显示如下错误, # ** Error: I:/programming/EDK/project...
The global set reset (GSR) signal is a special prerouted reset signal that holds the design in the initial state while the FPGA is being configured. After the configuration is complete, the GSR is released and all of the flip-flops and other resources now possess the INIT value. In additi...

Upgrade to the latest github master of Icarus Verilog to run the test bench.firmware/A simple test firmware. This runs the basic tests from tests/, some C code, tests IRQ handling and the multiply PCPI core.All the code in firmware/ is in the public domain. Simply copy whatever you ...
For interaction with RTL designs, it should have anotion of timeand some means to connect to the device under test. (In the early days ofe, “tick access” was used;portswere added a few years later.) For creating interesting scenarios while minimizing manual work, the HVL should haverand...
