The IA8044/IA8344 is a "plug-and-play" drop-in replacement for the original IC. InnovASIC produces replacement ICs using its MILESTM, or Managed IC Lifetime Extension System, cloning technology. This technology produces replacement ICs far more complex than "emulation" while ensuring they are compatible with the original IC. MILESTM captures the design of a clone so it can be produced even as silicon technology advances. MILESTM also verifies the clone against the original IC so that even the "undocumented features" are duplicated.……
