A process design kit (PDK) is supplied to a layout design tool. The PDK includes parameterized cells (Pcells) adapted to cause the layout design tool to automatically add labels to device layouts in the graphic design system (GDS) file that is being created by the layout design tool. Each corresponding label lists parameters used when creating the corresponding device layout. The GDS file is receive back from the layout design tool. The parameters from the labels is applied to corresponding ones of the Pcells within the PDK to create a device verification layout for each of the device layouts in the GDS file. Each of the device layouts in the GDS file is compared to a corresponding device verification layout. The device layouts within the GDS file that fail to match the corresponding device verification layout are thereby identified.

Pcell verification

Disclosed are a motion-sensitive field effect transistor (MSFET), a motion detection system, and a method. The MSFET includes a gate structure with a reservoir containing conductive fluid and gate electrode(s). Given position(s) of the gate electrode(s) and a fill level of the fluid within the reservoir, contact between the gate electrode(s) and the fluid depends upon the orientation the MSFET channel region relative to the top surface of the conductive fluid and the orientation of the MSFET channel region relative to the top surface of the conductive fluid depends upon position in space and/or movement of the MSFET and, particularly, position in space and/or movement of the chip on which the MSFET is formed. An electrical property of the MSFET in response to specific bias conditions varies depending on whether or not or to what extent the gate electrode(s) contact the fluid and is, thus, measurable for sensing chip motion.

Motion-sensitive field effect transistor, motion detection system, and method

Methods and systems generate seeds for public-private key pairs by determining a timestamp value associated with a process design kit (PDK) when a user of the PDK triggers a tool of the PDK while designing an integrated circuit device to have a physical unclonable function device (PUF). The methods and systems generate a first value by mapping the timestamp value to data of the user, generate a second value by mapping the timestamp value to configuration data of the PDK, and generate a third value by mapping the timestamp value to layout data of the PDK. A random number is then generated by applying a function to the first value, the second value, and the third value. A public-private encryption key pair is generated using the random number as a first seed number and using a second number generated by the number generation device as a second seed number.
