Programming programmable logic devices using hidden switches

摘要: A programming tool for programmable logic devices (PLDs), such as field gate arrays (FPGAs), supports the display of hidden-switch connections, in addition to conventional placed-switch, switch-box, and pseudo-arc connections. connection between two functional elements PLD is represented graphical displays generated by a curve (e.g., diagonal straight line) from jumper wire on first element another second element, where connected at one end an pin corresponding unconnected other end. that connections can be used program FPGAs PLDs having architectures were not previously supported tools do support
