搭建 SOPC 流程
1.cpu_0:
Component Library->Nios II Processor->Nios II/f( Reset Vector:Memory:cfi_flash_0,Exce
ption Vector: Memory:sdram_0,括号里的一会儿才能添加)->Next->Instrction Cache:4Kbytes,
Data Cache:2Kbytes->Next->Next->Next->Level 1->Next->Finish
2.tri_state_bridge_0:
Bridges and Adapters->Memory Mapped->Avalon-MM Tristate Bridge->Finish(一会儿还
要添加东西,在最后一个步骤中)
3.cfi_flash_0:
Memories and Memory Controlers->Flash->Flash Memory Interface(CFI)->Presets:Custo
m,Address Width(bits):22,Data Width(bits):8->Next->Setup:40,Wait:160,Hold:40,Units:ns->Finis
h.
4.sdram_0:
Memories and Memory Controlers->SDRAM->SDRAM Controller->Presets:Custom,Data
width Bits:16,Architecture Chip select:1,Banks:4,Address widths Row:12,Column:8->保持默认
->Finish
5. 设置 Reset Vector:Memory:
现在双击 cpu_0(第一个建的模块名字),设置 Reset Vector:Memory:cfi_flash_0,Exception
Vector: Memory:sdram_0->Finish
