Our favorite links for this topic area. Enjoy, fellow researchers! Questions, comments, new links? Email eewindow@aol.com!. In electronic design a semiconductor intellectual property core, IP block, IP core, or logic core is a reusable unit of logic, cell, or chip layout design and is also the intellectual property of one party. IP cores may be licensed to another party or can also be owned and used by a single party alone. The term is derived from the licensing of the patent and source code copyright intellectual property rights that subsist in the design. IP cores can be used as building blocks within ASIC chip designs or FPGA logic designs.
In digital-logic applications, IP cores are typically offered as generic gate netlists. The netlist is a boolean-algebra representation (gates, standard cells) of the IP's logical-function, analogous to an assembly-code listing for a high-level program application. The netlist protects the vendor against reverse-engineering, while maintaining portability to multiple foundry targets. Some vendors also offer synthesizable versions of their IP cores. Synthesizable cores are delivered in a hardware description language such as Verilog or VHDL, permitting customer modification (at the functional level). Both netlist and synthesizable cores are called 'soft cores', as both follow the SPR design-flow (synthesis, placement and route.)

Mark Twain quote for the day:
If I were to construct a God I would furnish Him with some way and qualities and characteristics which the Present lacks. He would not stoop to ask for any man's compliments, praises, flatteries; and He would be far above exacting them. I would have Him as self-respecting as the better sort of man in these regards.
He would not be a merchant, a trader. He would not buy these things. He would not sell, or offer to sell, temporary benefits of the joys of eternity for the product called worship. I would have Him as dignified as the better sort of man in this regard.
He would value no love but the love born of kindnesses conferred; not that born of benevolences contracted for. Repentance in a man's heart for a wrong done would cancel and annul that sin; and no verbal prayers for forgiveness be required or desired or expected of that man.
In His Bible there would be no Unforgiveable Sin. He would recognize in Himself the Author and Inventor of Sin and Author and Inventor of the Vehicle and Appliances for its commission; and would place the whole responsibility where it would of right belong: upon Himself, the only Sinner.
He would not be a jealous God-- a trait so small that even men despise it in each other.
He would not boast.
He would keep private Hs admirations of Himself; He would regard self-praise as unbecoming the dignity of his position.
He would not have the spirit of vengeance in His heart. Then it would not issue from His lips.
There would not be any hell-- except the one we live in from the cradle to the grave.
There would not be any heaven-- the kind described in the world's Bibles.
He would spend some of His eternities in trying to forgive Himself for making man unhappy when he could have made him happy with the same effort and he would spend the rest of them in studying astronomy.
