//
// Testbench: CPLD1 - SPI Formal Verification
// Project: NewCalBoard DIG
// Tool: Lattice Diamond Verilog-2001 / QuestaSim (Lattice OEM)
// Purpose: Formal verification of SPI protocol using explicit checks
//
// Interface: 4 wires only (i_sclk, i_cs, i_mosi, o_miso)
//
// Protocol:
// Write: [1][Addr:7b][Data:24b] = 32 bits
// Read: [0][Addr:7b][Don'tCare:24b] -> MISO returns [8'h00][24-bit rdata]
//
// Properties Verified (Explicit Checks):
// P1: Frame structure - 32-bit transfer on CS assertion
// P2: Write frame format - MSB first, write bit = 1
// P3: Read frame format - MSB first, read bit = 0
// P4: MISO response on read - 8'h00 prefix + 24-bit rdata
// P5: CS alignment - transfer completes within one CS low window
// P6: Register write persistence - written value survives subsequent reads
// P7: IDENT register read-only - always returns 24'h200110
// P8: MISO shift timing - data shifts out on falling edge (Mode 0)
// P9: No spurious MISO transitions during CS high
// P10: Sequential transfers - independent frame boundaries
// P11: Boundary conditions - min/max/alternate bit patterns
//
