6.8. Completion Timeout Interface

The completio timeout iteface idicates completio timeout evet to applicatio. The iteface povides the fuctio umbe ad tag umbe of the outstadig equest timed out.

Table 70.  Completio Timeout Iteface = 0 o 1, p0 = pot 0, ad p1 = pot 1
Note: Pot 1 is oly available i D-Seies FPGAs
Sigal Name Diectio Clock Domai Desciptio
p<>_ss_app_st_cplto_tvalid Output p<>_axi_lite_clk

p<>_ss_app_st_cplto_tvalid idicates that the completio timeout eceived fo a outstadig o-posted equest.

p<>_ss_app_st_cplto_tdata[48:0] Output p<>_axi_lite_clk
Caies completio timeout ifomatio.
  • Bit[9:0]: Tag umbe.
  • Bit[12:10]: PF umbe, idicates paet PF umbe of VF whe VF active is high else PF umbe of fuctio.
  • Bit[23:13]: VF umbe, idicates VF umbe whe VF active is high.
  • Bit[24]: VF active, idicates timeout is fo VF.
  • Bit[31:25]: Reseved.
  • Bit[43:32]: Tasfe legth i bytes (least sigificat 12-bits) of the expected completio that timed out fo the o-posted tasactio. Fo a split completio, it idicates the umbe of bytes emaiig to be deliveed whe the completio timed out (max legth is max ead equest size. Example: 4K Bytes = 2^12 bytes).
  • Bit[46:44]: Taffic class of the expected completio that timed out fo the o-posted tasactio.
  • Bit[48:47]: Attibute of the expected completio that timed out fo the o-posted tasactio. ID based odeig is ot suppoted.
    • [47]: No soop
    • [48]: Relaxed odeig
