？
什么意思，没有看懂！
是说在momentum中simulation吗？
还是说要优化长度？
比如我在Momentum中设一个微带天线，我想把他的长度表示为L，然后对L进行参数扫描
正好看到有这个东西：
Adding Layout Parameters
Layout components with layout parameters enable you to sweep, tune, or optimize
geometrical (shape) variations of planar layout objects. This includes:
? Typical dimensions such as lengths, widths, gaps, spacing, or diameters
? Interdependent layout modifications such as length and width varying
simultaneously
? Unconventional layout modifications such as varying port locations
There are two ways to create a parameterized layout:
? Using nominal/perturbed designs
? Using subnetwork parameters
细节就不多说了，查相关帮助吧
