常用的支持verilog的仿真器:VCS (synopsys), NC verilog/irun (cadence) , modesim(mentor)等等; 常用的支持spice的仿真器 :hspice (synopsys), Xa (synopsys), hsim(synopsys), finesim(synopsys),spectre(cadence)等等; hspice针对的是模块级的仿真,通常用于规模很小的电路,精度很高但速度非常慢。 Xa,hsim,fin...
finesim-vcs或hsim-vcs仿真方法与xa-vcs类似,只要将vcsAD.init中的xa指令换成finesim或hsim即可。 **3 **仿真结果 图4给出了我用finesim-vcs仿真pll的结果(根据xa自带的例子改的),可见a2d/d2a的转换是正确的。 Fig4. finesim-vcs仿真pll a2d/d2a转换 图5给出了我用finesim-vcs仿真pll的vctrl波形(模拟...
为了在digital-to-analog转换过程中的Verilog驱动强度,通过插值resistance map file中的值来计算等效电阻值。 默认情况下,该工具从PrimeSim XA、FineSim或PrimeSim安装目录中读取rmapAD.init map file,查找digital强度值的同等电阻映射范围,并计算该范围的平均值。 例如,考虑Verilog中的一个driver,它的驱动强度为6,并使...
