Title: Read data from external file
Post by prego64 on May 22^nd, 2006, 8:57am

Can somebody show me howto read in external data from a ASCII file into an array ?
For example: I have a file with three integer numbers (one number per line), that I want to assign to an array x[0]...x{2].

The documentation on fread() is very limited or non-existant.

Thanks !

Bernd

1364-2005 has $fscanf -- as well as more documentation on the system tasks for handling files than the AMS LRM does.
Some simulators already support the new 1364 for the digital engine and have brought that support over for AMS.

You might also consider the $table_model in AMS.

Is there any equivalent table model concept in VerilogA??

$table_model is in Verilog-A. (That is, it's in AMS, and the LRM doesn't exclude $table_model from the "analog only subset"; ergo, it is in Verilog-A.)
