PSoC 4 uses PSoC Creator as the integrated design environment to build a one chip solution. This is software that installs in a PC and allows for concurrent hardware and firmware design at PSoC systems. PSoC Creator uses compliments that are free embedded ICs represented by an icon on the PSoC Creator software. It uses these components to integrate multiple ICs and system interfaces into a single PSoC device. Component configuration tools are simple graphical user interfaces in PSoC Creator that are embedded in each component and are used to customize component parameters. PSoC 4 introduces a programmable analog block. The continuous time block-mini is used to implement op-amps, PGAs, comparators and more. There are over 60 components available in PSoC Creator for PSoC 4 designs.
