来源:互联网 发布:影响算法设计的因素 编辑:程序博客网 时间:2024/06/05 02:19
There are two variables in AXI Slave VIP that control the delay between the AREADY and AVALID:
MAX: dw_vip_axi_port_configuration :: m_nMaxDelay = 5000
MIN: m_nAvalidAreadyDelay = 0;
You can set your own Maximum delay in VMM env as below (using configuration):
class axiEnv extends vmm_env; virtual function void gen_cfg() ; super.gen_cfg(); vip_axi_slave_cfg.m_oPortCfg.m_nMaxDelay=3000; endfunction : gen_cfg endclass
also you can specify the minimum delay in Slave Responseras below (using object member):
task axiSlaveXactor::recv_write(); $display("###################################################"); $display($time,,"SLAVE receives a WRITE transaction"); $display("##################################################"); resp_trans.display("SLAVE RECV ::\t"); $display("\n"); /* Put the response object into the VIP slave input channel. */ resp_trans.m_nAvalidAreadyDelay =3; o_input_chan.put(resp_trans); endtask
