关于wattch模型的各种因子是从Hspice来的吗？

看wattch模型一直搞不明白这些参数的来源？

/* corresponds to 8um of m3 @ 225ff/um */
#define Cwordmetal    (1.8e-15 * (CSCALE * ASCALE))

/* corresponds to 16um of m2 @ 275ff/um */
#define Cbitmetal     (4.4e-15 * (CSCALE * ASCALE))

/* corresponds to 1um of m2 @ 275ff/um */
#define Cmetal        Cbitmetal/16

#define CM3metal        Cbitmetal/16
#define CM2metal        Cbitmetal/16

另外，论坛里面的hspice总是下载不完全
