Dear users
Thank you for your reply.
I found that my problem lies in the state machine it self, so i basically removed the RAM from my project and ran the synatizer using quartus.
The warning message has slighted change but may be its caused by the same mistake
Warning: Found 80 node(s) in clock paths which may be acting as ripple and/or gated clocks -- node(s) analyzed as buffer(s) resulting in clock skew
Regarding the RAMS timing what my state machine is doing is creating a vector throughout differnt stages of the process and when the vector is ready to be saved . The statemachine goes to a state that asserts the Clock input to the RAM to '1' and this is asserted 1 for one clock cycle of the clock in the state machine before returning to '0';
The other message i get is Warning: Timing Analysis is analyzing one or more combinational loops as latches Warning: Node "ramin[0]$latch" is a latch .. ... ....
Am i strucuring my VHDL code wrongly or somthing. I am using mentor graphic FPGA adavantge and have graphical created a state machine.
