// This file define a generic TSAR architecture with an IO network emulating
// an external bus (i.e. Hypertransport) to access external peripherals:
//
// - BROM : boot ROM
// - FBUF : Frame Buffer
// - MTTY : multi TTY (up to 15 channels)
// - MNIC : Network controller (up to 2 channels)
// - CDMA : Chained Buffer DMA controller (up to 4 channels)
// - BDEV : Dlock Device controler (1 channel)
//
// The internal physical address space is 40 bits.
//
// It contains a 2D mesh of XMAX*YMAX clusters, and the cluster index
// is encoded on 8 bits (X_WIDTH = 4 / Y_WIDTH = 4) whatever the mesh size.
//
// 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 is emulating 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
//    6 external peripheral controllers.
//    (VCI ADDDRESS = 40 bits / VCI DATA width = 64 bits)
//
// The external peripherals IRQs are connected to the XICU component
// in cluster(0,0): therefore, the number of channels for the external
// peripherals (MTTY, MNIC, CDMA) is limited by the number of IRQ ports...
//
// In cluster(0,0), the XICU HWI input ports are connected as follow:
// - IRQ_IN[0]  to IRQ_IN[7]  grounded (reserved for PTI or SWI)
// - IRQ_IN[8]  to IRQ_IN[9]  are connected to 2 NIC_RX channels.
// - IRQ_IN[10] to IRQ_IN[11] are connected to 2 NIC_TX channels.
// - IRQ_IN[12] to IRQ_IN[15] are connected to 4 CDMA channels
// - IRQ_IN[16] to IRQ_IN[30] are connected to 15 TTY channels
// - IRQ_IN[31]               is connected to BDEV
// In other clusters, the XICU HWI input ports are grounded.
//
// 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).
// The number of clusters cannot be larger than 256.
// The number of processors per cluster cannot be larger than 4.
//
// - It uses two dspin_local_crossbar per cluster to implement the
//   local interconnect correponding to the INT network.
// - It uses two 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_dma 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 :
// - XMAX        : number of clusters in a row (power of 2)
// - YMAX        : number of clusters in a column (power of 2)
// - CLUSTER_SIZE     : size of the segment allocated to a cluster
// - NB_PROCS_MAX     : number of processors per cluster (power of 2)
// - NB_DMA_CHANNELS  : number of DMA channels per cluster (< 9)
// - NB_TTY_CHANNELS  : number of TTY channels in I/O network (< 16)
// - NB_NIC_CHANNELS  : number of NIC channels in I/O network (< 9)
//
// 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
// - FBUF_X_SIZE      : width of frame buffer (pixels)
// - FBUF_Y_SIZE      : heigth of frame buffer (lines)
// - BDEV_SECTOR_SIZE : block size for block drvice
// - BDEV_IMAGE_NAME  : file pathname for block device
// - NIC_RX_NAME      : file pathname for NIC received packets
// - NIC_TX_NAME      : file pathname for NIC transmited packets
// - NIC_TIMEOUT      : max number of cycles before closing a container
//
// 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          |
//      |x_width|y_width|---|  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 |
//      |x_width|y_width|---|  6   |

//   They have the same local index, but two different cluster indexes.
// As cluster_iob0 and cluster_iob1 contain both internal initiators
// and external initiators, they must have different local indexes.
// Consequence: For a local interconnect, the INI_ID port index
// is NOT equal to the SRCID local index, and the local interconnect
