Latest Patents

Haggai holds a patent titled "Constraint programming based method for bus-aware macro-block pin placement in a hierarchical integrated circuit layout." This patent describes a method for assigning pins to macro-blocks of an Integrated Circuit (IC) chip. The macro-block pin assignments are automatically placed using Constraint Programming (CP) techniques, which position the pins on the periphery of a macro-block. The method takes into account bus-ordering and pin-spacing constraints, considering all the nets forming the IC design simultaneously. The CP formulation includes modeling detailed and discrete constraints required to achieve an optimal pin assignment. A stochastic CSP solver is utilized to define the cost function on search points, providing full assignments to all the variables. Ultimately, the macro-block pins are moved to computed locations.
