Analog hardware description languages

With the growing trend in ASIC design to include more analog functions on chip, various design support and automation efforts have arisen to address the analog design concerns. Existing hardware description languages have been widely used for design representation, documentation and transfer mainly in the digital domain, with standards such as VHDL being fairly mature. In this paper we present two efforts that are underway in developing standardized analog hardware description languages. One of these is a new language called MHDL for analog and mixed-signal representation while the second is aimed at providing analog extensions to the existing VHDL standard.<
