Hi,
Instead of creating twelve Parallel input output ports (PIO) in Qsys/SOPC, is there any way I could vectorise many parallel input output ports (12 PIOs for example) into a single component in Qsys or SOPC?
Each PIO consists of 12 bits.
After creating the Nios system, I am going to include the Nios system block in the schematic in Quartus.
I need to feed the twelve PIOs into one single bus line in the schematic block in Quartus II. So I thought I want to combine the twelves PIOs so that in the NIos system block, it will only show one PIO instead of twelve.
I attached the image:
adc[1..12][11..0] is the 12 signals, each with 12 bits
in Nios system block, adc_v1_export is single signal, with 12 bits
I want to connect
What I have tried : I followed the advice in this link (
http://www.alteraforum.com/forum/showthread.php?t=20876) but i got the following error (Error (275024): Width mismatch in port "adc_v1_export[11..0]" of instance "inst14" and type nios_system -- source is ""adc[0]""
).
Thank you
