International Classification:

G06F 17/50

US Classification:

716 12

Abstract:

In one embodiment of the invention, an object oriented autorouter is disclosed for routing nets in a circuit. The object oriented autorouter includes a routing data model (RDM); at least one routing engine, such as a single connection router (SCR), a topographical (TOPO) transformation engine, and a detail geometric (DETAIL) engine, and a command and control module (CCM) coupled together. The RDM reads and write data with a design database as well as reading one or more object oriented design constraints. Each of the routing engines have at least one action to operate on the design database to improve compliance of the circuit to a constraint. The CCM controls the overall routing process of the nets in the circuit and includes at least one director to invoke at least one of the routing engines to achieve compliance with one or more constraints.

Abstract:

Methods, systems, and media for calibrating a display device are provided. In some embodiments, the methods comprise: causing a first test stream to be displayed on the display device; capturing, using a hardware processor, at least one screenshot of the first test stream displayed on the display device; detecting, using the hardware processor, a first test pattern in the screenshot; determining, using the hardware processor, whether the first test pattern contains a distortion; and generating, using the hardware processor, a set of instructions to calibrate the display device in response to determining that the first test pattern contains a distortion.
