Users of the FC203A firmware module will reference the Diamond .fcd file (top level) from the
fc203a\ above.
4. USAGE
The firmware module is instantiated in a Diamond/FPGA configuration file as follows:
! declare tasks
!
task chop0
ins=5 outs=3 file="..\fc203a\fc203a.fcd"
!
! place tasks on FPGA
!
place chop0
<fpga>
!
! connect dataflow
!
connect ? <user_1>[w]
chop0[0]
connect ? <user_1>[x] chop0[1]
connect ? <user_1>[y] chop0[2]
connect ? <user_1>[z] chop0[3]
connect ? <user_cfg>[n] chop0[4]
connect ? chop0[0] <user_2>[a]
connect ? chop0[1] <user_3>[b]
connect ? chop0[2] <user_stat>[c]
Where
<user_1> is a four-channel data source, <user_2> and <user_3> are data-sink
tasks, and <user_stat> is a status-sink task. <user_cfg> is a connection which supplies
the 32-bit configuration control word.
