Method for flexibly designing memory use in integrated circuits

摘要

A method for designing and using a partially manufactured semiconductor product is disclosed. The partially manufactured semiconductor product, referred to as a slice, contains a fabric of configurable transistors and at least an area of embedded memory. The method contemplates that a range of processors, processing elements, processing circuits exists which might be manufactured as a hardmacs or configured from the transistor fabric of the slice. The method then evaluates all the memory requirements of all the processors in the range to create a memory superset to be embedded into the slice. The memory superset can then be mapped and routed to a particular memory for one of the processors within the range; ports can be mapped and routed to access the selected portions of the memory superset. If any memory is not used, then it and/or its adjoining transistor fabric can become a landing zone for other functions or registers or memories.
