Pin density in vlsi
WebA pin grid array(PGA) is a type of integrated circuit packaging. In a PGA, the package is square or rectangular, and the pins are arranged in a regular array on the underside of the package. The pins are commonly spaced 2.54 mm (0.1") apart,[1]and may or may not cover the entire underside of the package. http://www.ee.ncu.edu.tw/~jfli/soctest/lecture/ch02.pdf

Pin Density Technique is preferred over other Congestion estimation and reduction techniques because of its uniqueness in altering the number of pins in accordance with desired architecture constraints and it provides effective results compared to other techniques.
WebDefinition. Electromigration is the movement of atoms based on the flow of current through a material. If the current density is high enough, the heat dissipated within the material will repeatedly break atoms from the structure and move them. This will create both ‘vacancies’ and ‘deposits’. The vacancies can grow and eventually break ... the low fiveWebBelow is the pin density report of the design with and without multibit.
