| Description |
Section 17.2.4.4 describes the $fread system function as reading data into the reg myreg or the memory mem. This might be interpreted as meaning that myreg must be declared as a reg. In fact, this appears to be an archaic use of the term "reg" and should have referred to a "variable". There is no reason that $fread should not be able to read into an integer or time variable. It should even be possible to read into a real or realtime variable. |

Agreed, but I would like to widen this item into all of Section 17. "reg" is used in many places too restrictively. For example, in 17.2.1, paragraph 2, it says, "filename is a character string, or a reg containing a character string that names the file to be opened." There is no good reason that a vector wire should not be able to be used here as well as a reg. -- Shalom Bresticker Shalom.Bresticker@motorola.com Design & Reuse Methodology Tel: +972 9 9522268 Motorola Semiconductor Israel, Ltd.
