// This file define a generic TSAR architecture with an external IO network 
// emulating a PCI or Hypertransport I/O bus to access 7 external peripherals:
//
// - BROM : boot ROM
// - FBUF : Frame Buffer
// - MTTY : multi TTY (one channel)
// - MNIC : Network controller (up to 2 channels)
// - CDMA : Chained Buffer DMA controller (up to 4 channels)
// - BDEV : Dlock Device controler (one channel)
// - IOPI : HWI to SWI translator.
//
// This I/0 bus is connected to internal address space through two IOB bridges
// located in cluster[0][0] and cluster[X_SIZE-1][Åž_SIZE-1].
// 
// The internal physical address space is 40 bits, and the cluster index
// is defined by the 8 MSB bits, using a fixed format: X is encoded on 4 bits,
// Y is encoded on 4 bits, whatever the actual mesh size.
// => at most 16 * 16 clusters. Each cluster contains up to 4 processors.
//
// It contains 3 networks:
//
// 1) the "INT" network supports Read/Write transactions
//    between processors and L2 caches or peripherals.
//    (VCI ADDDRESS = 40 bits / VCI DATA width = 32 bits)
//    It supports also coherence transactions between L1 & L2 caches.
// 3) the "RAM" network emulates the 3D network between L2 caches
//    and L3 caches, and is implemented as a 2D mesh between the L2 caches,
//    the two IO bridges and the physical RAMs disributed in all clusters.
//    (VCI ADDRESS = 40 bits / VCI DATA = 64 bits)
// 4) the IOX network connects the two IO bridge components to the
//    7 external peripheral controllers.
//    (VCI ADDDRESS = 40 bits / VCI DATA width = 64 bits)
//
// The external peripherals HWI IRQs are translated to WTI IRQs by the
// external IOPIC component, that must be configured by the OS to route
// these WTI IRQS to one or several internal XICU components.
// - IOPIC HWI[1:0]     connected to IRQ_NIC_RX[1:0]
// - IOPIC HWI[3:2]     connected to IRQ_NIC_TX[1:0]
// - IOPIC HWI[7:4]     connected to IRQ_CMA_TX[3:0]]
// - IOPIC HWI[8]       connected to IRQ_BDEV
// - IOPIC HWI[31:16]   connected to IRQ_TTY_RX[15:0]
//
// Besides the external peripherals, each cluster contains one XICU component,
// and one MWMR coprocessor.
// The XICU component is mainly used to handle WTI IRQs, as only the MMC HWI IRQ
// is connected to XICU in each cluster.
//
// All clusters are identical, but cluster(0,0) and cluster(XMAX-1,YMAX-1)
// contain an extra IO bridge component. These IOB0 & IOB1 components are
// connected to the three networks (INT, RAM, IOX).
//
// - It uses two dspin_local_crossbar per cluster to implement the
//   local interconnect correponding to the INT network.
// - It uses three dspin_local_crossbar per cluster to implement the
//   local interconnect correponding to the coherence INT network.
// - It uses two virtual_dspin_router per cluster to implement
//   the INT network (routing both the direct and coherence trafic).
// - It uses two dspin_router per cluster to implement the RAM network.
// - It uses the vci_cc_vcache_wrapper.
// - It uses the vci_mem_cache.
// - It contains one vci_xicu and one vci_multi_mwmr per cluster.
// - It contains one vci_simple ram per cluster to model the L3 cache.
//
// The TsarIobCluster component is defined in files
// tsar_iob_cluster.* (with * = cpp, h, sd)
//
// The main hardware parameters must be defined in the hard_config.h file :
// - X_SIZE           : number of clusters in a row
// - Y_SIZE           : number of clusters in a column
// - NB_PROCS_MAX     : number of processors per cluster (power of 2)
// - NB_TTY_CHANNELS  : number of TTY channels in I/O network (up to 16)
// - NB_NIC_CHANNELS  : number of NIC channels in I/O network (up to 2)
// - NB_CMA_CHANNELS  : number of CMA channels in I/O network (up to 4)
// - FBUF_X_SIZE      : width of frame buffer (pixels)
// - FBUF_Y_SIZE      : heigth of frame buffer (lines)
// - XCU_NB_INPUTS    : number of HWIs = number of WTIs = number of PTIs
//
// Some secondary hardware parameters must be defined in this top.cpp file:
// - XRAM_LATENCY     : external ram latency
// - MEMC_WAYS        : L2 cache number of ways
// - MEMC_SETS        : L2 cache number of sets
// - L1_IWAYS
// - L1_ISETS
// - L1_DWAYS
// - L1_DSETS
// - BDEV_IMAGE_NAME  : file pathname for block device
//
// General policy for 40 bits physical address decoding:
// All physical segments base addresses are multiple of 1 Mbytes
// (=> the 24 LSB bits = 0, and the 16 MSB bits define the target)
// The (x_width + y_width) MSB bits (left aligned) define
// the cluster index, and the LADR bits define the local index:
//      |X_ID|Y_ID|  LADR  |     OFFSET          |
//      |  4 |  4 |   8    |       24            |
//
// General policy for 14 bits SRCID decoding:
// Each component is identified by (x_id, y_id, l_id) tuple.
//      |X_ID|Y_ID| L_ID |
//      |  4 |  4 |  6   |
