integrating an adder to my architecture (cortex m0)

[mariouma]

Hi,i'm using a nexys4,am trying to interface an adder with my arm architecture using the labs given by arm community

so,i defined the memory map in the AHBDCD.v.....MUX_SEL and HSEL signal

however the simulation don't work

 i suggest that i can't define the assign HSEL_s10

AHBDCD.v------>

//REFER CM0-DS REFERENC MANUAL FOR RAM & PERIPHERAL MEMORY MAP
//        //MEMORY MAP --> START ADDR         END ADDR     SIZE 
assign HSEL_S0 = dec[0];   //MEMORY MAP --> 0x0000_0000 to 0x00FF_FFFF  16MB
assign HSEL_S1 = dec[1];   //MEMORY MAP --> 0x5000_0000 to 0x50FF_FFFF  16MB    
assign HSEL_S2 = dec[2];   //MEMORY MAP --> 0x5100_0000 to 0x51FF_FFFF  16MB
assign HSEL_S3 = dec[3];   //MEMORY MAP --> 0x5200_0000 to 0x52FF_FFFF  16MB
assign HSEL_S4 = dec[4];   //MEMORY MAP --> 0x5300_0000 to 0x53FF_FFFF  16MB
assign HSEL_S5 = dec[5];   //MEMORY MAP --> 0x5400_0000 to 0x54FF_FFFF  16MB
assign HSEL_S6 = dec[6];   //MEMORY MAP --> 0x5500_0000 to 0x55FF_FFFF  16MB
assign HSEL_S7 = dec[7];   //MEMORY MAP --> 0x5600_0000 to 0x56FF_FFFF  16MB
assign HSEL_S8 = dec[8];   //MEMORY MAP --> 0x5700_0000 to 0x57FF_FFFF  16MB
assign HSEL_S9 = dec[9];   //MEMORY MAP --> 0x5800_0000 to 0x58FF_FFFF  16MB
assign HSEL_S10 = dec[10];   //MEMORY MAP --> 0x5900_0000 to 0x59FF_FFFF  16MB
assign HSEL_NOMAP = dec[15]; //REST OF REGION NOT COVERED ABOVE

Hi mariouma,

I have asked some of our applications engineers to see if they are familiar with this; they'll get back to you here on the forum.

Thanks,

Hi mariouma,

Unfortunately we haven't really had any experience working with the Cortex M0 processor, Your assign syntax looks correct, but past that I don't think we will be much help. I would try reaching out to the ARM community with this question.

Sorry I couldn't help out more!
