Signal

Type

Description

vawvalid_ vn<x>[a]

Input

Token request valid. This signal indicates that the master requests a token.

vawready_ vn<x>

Output

Token request accepted. This signal indicates that the slave is ready to accept an address and associated control signals.

vawqos_ vn<x>

Input

Quality of service value. Non-standard AXI3 signal.

vwvalid_ vn<x>

Input

Token request valid. This signal indicates that the master requests a token.

vwready_ vn<x>

Output

Token request accepted. This signal indicates that the slave is ready to accept a write data transfer and associated control signals.

varvalid_ vn<x>

Input

Token request valid. This signal indicates that the master requests a token.

varready_ vn<x>

Output

Token request accepted. This signal indicates that the slave is ready to accept an address and associated control signals.

varqos_ vn<x>

Input

Quality of service value. Non-standard AXI3 signal.
qvn_prealloc_wInputWrite address token pre-allocation. This bus is 4 bits wide. Each bit specifies the pre-allocation of the corresponding virtual network.
qvn_prealloc_rInputRead address token pre-allocation. This bus is 4 bits wide. Each bit specifies the pre-allocation of the corresponding virtual network.

[a] <x> is the virtual network number for the signals in this table.
