更新文档

功能测试

  • axi4里包含了封装成axi接口的CPU,可以通过soc_axi_func测试

性能测试

  • 复制golden_traceperf_test_v0.01目录下

  • 依照性能测试说明文档1.5.1方法一的步骤仿真指定程序

  • 修改soc_axi_perftestbench文件

35  `define TRACE_REF_FILE "../../../../../../../golden_trace/golden_traceX.txt", 	X为仿真测例号
39  `define CONFREG_OPEN_TRACE 1'b1
  • 修改test_bench的检测时机,从上沿改成电平检测
120 always @(cpu_clk)
149 always @(cpu_clk)
250 always @(cpu_clk)

关键路径
