I am using the web edition of quartus 2 version 9.1. I would like to add a 7489 ram to a schematic I have been working on. I do not see this chip in the maxplus2 library, but there are a host of other 74 series chips. Where can I find a symbol for a 7489 RAM? 

 

Thanks!

I'm afraid you will have to model this component in AHDL/VHDL/Verilog and provide a symbol yourself. Also, be aware that open-collector outputs are not supported internal to the FPGA. 

 

Best regards,
