Test Plan for Interface and Node Logic General - Synchronizers--test with fast and slow pb_clk - Test PROM ctlsvchip - eosi decoding (interrupt and scan status) - dncntr16 (PBus xfer count) - opcode register - next address pointer - control regs - 8 bit mode - immediate mode - lengths of 0-6 - read (noop) - host wait - host jump - cam wait (for end of scan) - slave regs - cam reset - interface reset - timeout - interrupts - soft interrupt - pbus timeout - sbus error - cam interrupt fsmchip - SBus bug fix - end of scan decode (sctlfsm) - sparfsm - sctlfsm - scamwrfsm - scamrdfsm - pctlfsm - pwrfsm - prdfsm - SBus error decode dataregs - slave decoding - data out regs - normal mode - 8 bit mode - data in regs - data available flags - parity generation - immediate mode - block mode Node logic - variables: - read/write - iosel high time (1-6) - eofout--16 possible values at each edge of iosel - rs1in--16 possible values at each edge of iosel - ldata--16 possible values at each edge of iosel - rdata--16 possible values at each edge of iosel
