7 years agoALTASMI_PARALLEL in full synchro design. Can I use the same clock and edge (rising edge ) for clkin and the rest of the design?
I use a ALTASMI_PARALLEL and a ALTEREMOTE_UPDATE megafunctions in a cyclone III. All the design is full synchro and use a rising edge of a 12MHz clock. I want to know if it's possible to use the same...

7 years agoThank you for your answer.
When you said same clock source, that imply the same front edge, that right?
It's not clear for me when I check the Active Serial Memory Interface (ALTASMI_PARALLEL) Megafunction
User Guide (UG-ALT1005-4.2) .
For example for a Write :

What is the best solution to manage inputs signals (write , wren, shift_bytes, data_in.....) and to respect the propose timing?
1/ using clk positive edge for signals generation and clk negative edge for ALTASMI_PARALLEL clkin with constraints on Clk Frequency.
Or
2/ using same clock positive edge for both with appropriate timing constraints on ALTASMI_PARALLEL. In this case, can-you help me to define the appropriate constraints for the IP?
Same question for the ALTEREMOTE_UPDATE IP.
Thank you for your help.
