Not at this time. For clarity of terminology, I would say that what we need is not a component that models the PCI bus per se, but rather: - a programmable mapper component (for use in implementing the reconfigurable address mapping), *OR* - a memory-access-broadcasting component (a special mapper that broadcasts each incoming access to a number of slaves, just as would happen on a real bus, instead of decoding the access by address to a single slave) - models of subsets of PCI bus controller chips (their control registers) - a utility component class that implements common functions of generic PCI bus slaves vs. masters, in specific by exposing sid models of the standard physical interfaces (buses, interrupt lines, address-space selection signals, control signals). - a pair of sid components for bridging PCI-to-plain-sid-bus and vice-versa - FChE -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE6X8jTVZbdDOm/ZT0RAhKVAJ9x/7e1vXLwRDNfAPjCrjKpANsZcgCfQKb2 7T1FmWIc0bxvuYFfDfYJzBA= =azXg -----END PGP SIGNATURE-----
