////注释 ：窗口定义,这里窗口的定义最关键，新生成的dummy在窗口的0.0原点开始，且第一根为红色。所以在stdcell区域就要找到第一更是红色的M4，且离这个M4的间距为Y上移0.064的M的起点位置为窗口的原始位置
//**the location for the first  fillgen=red  dummy of (DM4_O)  is POLGON LL ,  the pitch is  0.084,and space is 0.064  between first  fillgen and M4(vdd/vss)
// mesured the space of between  the first red M4 in the stdcell region and  polygon org  coordinate .which is 0.064
