Disclosed are apparatus and methods for providing a serial interface with shared datapaths. The apparatus and methods share or re-use components from multiple lower-speed datapaths so as to efficiently provide a higher-speed datapath. In one embodiment, physical coding sublayer circuitry of the lower-speed datapaths is also used by the higher-speed datapath. In another embodiment, physical media access circuitry of the lower-speed data paths is also used by the higher-speed datapath. Other embodiments, aspects and features are also disclosed.

A high speed serial interface comprises a rectilinear array of rows and columns of contact sites on a substrate. In the first four columns, pairs of transmitter and receiver contacts alternate row-by-row with pairs of ground contacts In the fifth column, there is a permanent (or hard) ground contact adjacent to each transmitter or receiver contact pair located in a row in the third and fourth columns and the remaining contacts in the fifth column are general purpose input/output (GPIO) contacts. As a result, up to 50 percent of the contacts in the fifth column may be GPIO contacts. In the sixth column, all the contacts are GPIO contacts.

A charge pump circuit includes switch circuit modules and current modules. The number of switch circuit modules that are coupled to receive current from one of the current modules is variable. The output current of the charge pump circuit increases as more of the switch circuit modules are coupled to receive current from the current modules. The net on-resistance of the switch circuit modules decreases as more of the switch circuit modules are coupled to receive current from the current modules. Charge coupling caused by the net parasitic gate-to-drain capacitance of switching transistors in the switch circuit modules is reduced at smaller output current settings of the charge pump circuit.

A method for determining clock uncertainties is provided. The method includes identifying clock transfer types between registers from an integrated circuit design and identifying contributors to the clock uncertainties for each of the clock transfers. The jitter associated with each identified contributor is calculated for both set-up time and hold time. This calculated jitter is incorporated into a slack calculation to determine whether timing constraints are met for a circuit design.

In some embodiments, an apparatus includes a network device configured to receive an anomaly database of a first image that stores a set of differences between the first image and a base image. The network device is configured to compare the anomaly database of the first image with an anomaly database of a second image storing a set of differences between the second image and the base image to determine if the first and second images include at least one incompatible critical feature or incompatible non-critical feature. The network device is configured to send a signal associated with a first action if the first and second images include the at least one incompatible critical feature. The network device is configured to send a signal associated with a second action different from the first action if the first and second images include the at least one incompatible non-critical feature.
