16BIT memory

[Altera_Forum]

Hello there! 

 Because of insufficient pins, i was forced to use a 16 bit SRAM memory. Now i want to run the program from this memory. i am using the cypress 32bit mem megafunction and have used a doubled clock for memory access. i asked altera for the documentations but i did not get any.   has someone done this before and can help me with this?  thanks

You should create a custom component with no HDL files, make its slave an Altera Tristate Bus type, with memory addressing (instead of "native/register" addressing), and add whatever signals you need to hook up to the memory (CE=chipselect, WE=write, OE=read, A[...]=address, D[...][]=data). Then add it and an Altera Tristate Bridge to your design, hook it all up, and you should be good.

no, i just used doubled clock frequency for the memory. i have no exp creating a custom component. i will try it now and let u know. thank u! 

 The NIOS IDE says that byteblaster II is not supported and may cause communications problems. Could this be the problem, because i see opcode fetches happening in the Disassembly window...
