Abstract
In-circuit-emulation of an integrated circuit permits location and identification of optional emulation resources. Each emulation resource is assigned a memory address. The in-circuit-emulation generates a special memory access to memory addresses. If the special memory access corresponds to the address of an emulation resource, the emulation resource responds with an acknowledgement and a corresponding identification number. Nonemulation circuits do not respond to the special memory access. This technique permits manufacture of plural integrated circuits with corresponding sets of emulation resources, where an emulation program can determine the available resources for the particular integrated circuit. The emulation resources preferrably includes a set of emulation resources common to all integrated circuits with predetermined memory addresses and a predetermined identification numbers as well as optional emulation resources. The emulation program can locate and identify all emulation resources by generating the special memory access to each address of a range of addresses.
