7064BLC44-7 problem with pin setup in Quartus

Hello,

I'm trying to import old Max+ project into quartys 5.1. This is for device 7064BLC44-7. Quartus doesn't have this device on the list, the closest I can get is 7064BTC44-7. But when I try to compile the project it says that I have problem with pin assignments. For example:

Error: Node "filter[1]" assigned to PIN_40 is a dedicated input pin, but you cannot assign an output/bidir pin, input register, or macrocell to a dedicated input pin.

I also tried it with new Quartus 9.1, but got exactly the same result.

I'm stuck, don't know what to do? Can any one suggest something?

Regards,

Maris Mols

    It seems that the 7064BLC44 is the forgotten device :-)

    7064BLC is the plcc version and 7064BTC the tqfp

    if you compare both pinouts you will see that they differ where they start to count the pins

    7064TLC44 pin 1 is 7064BLC44 pin 7

    7064TLC44 pin 2 is 7064BLC44 pin 8

    Quartus knows the EPM764AELC44-7 but i am quit unshure if you can compile for this device and run it on your target.

    you could give it a try and / or ask mysupport or your fae

    or hopefully somebody else knows a solution

    Thank you for information.

    Does that mean it would be enough to change the pin numbers to compile this project as BTC instead of BLC. Where can I find pin mapping information from one chip to another?

    no, quartus must know what device you use, you can't just change the pin mapping.

    you could give your design a try with setting quartus up for a EPM764AELC44-7 instead of your EPM7064BLC44-7 but i am unshure if that will work correctly.
