直接在VerilogA模型中写入随机函数,对于特定参数进行设定标准差下的高斯分布变化,然后进行多次仿真,进而完成蒙特卡洛仿真。 这种思路在理论上可行的,根据《Cadence® Verilog®-A Language Reference》[1]P147所示,我们可以利用$arandom函数来进行直接蒙卡仿真。 事实上,在cadence官方的在线支持中也有给出一个直接进行V...

一般而言,单元库包含的逻辑信息有以下几项: ① Cell Schematic,用于电路综合,以便产生逻辑电路的网表(Netlist)。 ② Timing Model,描述各逻辑门精确时序模型,设计时提取逻辑门内寄生电阻、电容进行仿真,从而建立各逻辑门的实际延迟参数。其中包含门延迟、输入/输出延迟和连线延迟等;此数据用于综合后功能仿真以验证电路...
In the course, you learn how to model analog block operation as discrete real data to improve top-level verification performance using SVrealdata type andnettypes. It stresses SystemVerilog 2012 Extended Nettype Capabilities (built-in, UDT/UDR) and Interconnects. You learn to use the Cadence®...

7月底在美国举行的2006年DAC上Cadence的前CEO,Joe Costello说在开源并不适合EDA行业,原因是从事这个行业的人太少,而开源需要大量散落在网络各个角落的工程师共同开发与推进。EDA市场是商业软件的天下,Cadence,Sysnopsys,Mentor Graphics和Magma占有了绝大部分的市场份额。问题在于这个市场到达40亿美元就有些停滞不前了...
