Signal Name Direction Width Description

avl_out_clk Output 1 Connect this signal to the input Avalon interface of

another Altera PHYLite for Parallel Interfaces IP core or

the Arria 10 External Memory Interfaces IP.

avl_out_reset_n Output 1 Connect this signal to the input Avalon interface of

another Altera PHYLite for Parallel Interfaces IP core or

the Arria 10 External Memory Interfaces IP.

avl_out_read Output 1 Indicates read transaction.

avl_out_write Output 1 Indicates write transaction.

avl_out_byteenable Output 4 Controls which bytes should be written on avl_out_

writedata.

avl_out_address Output 28 Avalon address (in byte granularity). Value is identical to

avl_address but with zeroes padded on the LSBs.

avl_out_readdata Input 32 The data packet associated with avl_out_readdata_

valid.

avl_out_readdata_

valid

Input 1 Indicates that read data has returned.

Example Design

The Altera PHYLite for Parallel Interfaces IP core is able to generate an example design that matches the

same configuration chosen for the IP. The example design is a simple design that does not target any

specific application; however you can use the example design as a reference on how to instantiate the IP

core and what behavior to expect in a simulation.

Note:

The .qsys files are for internal use during example design generation only. You should not edit the

files.
