Analog Layout Design

PS90
PS90 over 10 years ago

I have made an analog circuit in mosfet weak inversion region. The aspect ratio of many mosfets are like (W/L)=(0.4u/15u). During DRC run(in layout), the virtuoso gives errors "13A1: P+SD to NW tap spacing must be <=10um" and "13A3: N+SD to Psub tap spacing must be 10<=um", for almost all the  mosfets. Please help for diagnosing this error.
