I have problem using DPRAM.. I am connecting NIOS II with portB of altsyncram, portA of altsyncram with external pin for my DPRAM. I can connect NIOS with portB of altsyscram using SOPC Builder, but I have problem connecting portA of altsyncram to external pin. What I need to know is how to connect: data_a address_a wren_a q_a and addr (input) data (bidir) cs_n (input) rw_n (input) I tried connecting as follows: addr <-> address_a (cs_n nor rw_n)<->(wren_a) and tried connecting data <-> (data_a, q_a) using lpm_bustri or tri, but cannot read & write well. What actually happens is, it writes unexpected data to unexpected places when I try read/write.. I think my problem is the way I am connecting data <-> (data_a,q_a) I also tried connecting the expernal pin to dff, but would not work. Any advice would be great.
