Instruction Parameters

The parser searches the template list first.

• If a template with the specified name is not found, it searches the local generation procedure structure variable list.

• If a local generation procedure structure variable is not found, the parser searches the global structure variable list.

• If a structure variable is not found, the system reports a parser error.

The named instruction parameters are:

• Delay: Delay time (in nanoseconds) to wait before sending the packet.

• Override: Specifies a bitmap that instructs the Voyager USB 3.2 Exerciser to set values for the CRC-5, CRC-16, CRC-32 and Length fieldsfromthe packet templateand insert erroneous values for Delayed and Header Sequence Number fields from the bitmap, rather than calculating them automatically.

The default value for the Delay parameter is UNDEFINED (0xFFFFFFFF), so that a delay between packets is taken from the PktDelay global setting (which is 0 by default).

The default value for Override isOVR_NONE.

Delimit instruction parameters use a comma, as shown in the following examples
(“TX_PACKET” after the Send keyword in the examples below denotes some template name.)

To send a TX_Packet with Delay = 0 and No Override: SendTX_PACKET( Delay = 0, Override = OVR_NONE )

To send a TX_Packet with Delay = 200 ns and No Override: SendTX_PACKET( 200, OVR_NONE )

To send a TX_Packet with Delay = 400 ns: SendTX_PACKET( 400 )

To send a TX_Packet with Delay = 20 ns and Override CRC-5:

SendTX_PACKET( Delay = 20, Override = OVR_CRC5)
OR
SendTX_PACKET( 20, OVR_CRC5)

To send a TX_Packet with Delay = 40 ns and Override Length and CRC32: SendTX_PACKET( 40, OVR_LEN | OVR_CRC32 )

To send a TX_Packet with delay = 250 ns and Override All: Send TX_PACKET(Delay = 250, Override = OVR_ALL )

Examples

Main
{
    # Send a packet based on the template 'TX_PACKET' 
    # using default values.
SendTX_PACKET

    # Send a packet based on the template 'TX_PACKET' 
    # using default values overriding some default 
    # instruction parameters.
SendTX_PACKET ( Delay = 100 )
SendTX_PACKET( 100 )  # the same as the previous instruction

    # Send a packet based on the template 'TX_PACKET_1' 
    # using overridden values and changing the default delay setting.
SendTX_PACKET_1

    }

    ( Delay = 100 )  # Set the 'Delay' to 100.

    # Send a packet and use the provided CRC32 instead of 
    # automatic calculation.
SendTX_PACKET
    {
        DevAddr  = 0x80
        Endp     = 2
        Data     = { AA BB CC DD }
        CRC32      = 0x11223344  # This value is used as CRC32 
                                 # for this packet.
    }
    (Override = OVR_CRC32)
