Initialization file when infer a RAM IP

Hi, I am using VHDL code to infer a RAM IP of stratix 10. There are two choices to initialize RAM: use a function as provided by the VHDL template, or use attribute as shown in following: type mem_...

I don't understand. If you don't want to initialize the RAM, simply don't include the attribute in your code.

    Hi,

    We use the RAM as a generic_ram in our project. And the initialization file is optional depends how the upper layer uses it. And we also have other project use the generic_ram as well which is on Arria 10. They are still using the old generic_ram which is not inferring RAM with VHDL, but setting ip parameters of RAM IP. They have the option to use or not use initialization file. For the compatibility, we also need this option.We are trying to use inferring RAM because this method is device independent and parameters independent, and it is easier to maintain when we move from device to another, such as the situation we have now is moving from Arria 10 to Stratix 10, there are a lot of extra work to update the device related primitives. Please let me know if you have any idea.

    Thanks,

    Xin
