[sv-cc] String format

Hi,

 

I would like to request that the specification clarify how strings are
returned

in some PLI functions.

 

The tf_getcstringp() clearly states:

 

a) Eliminating leading zeros

b) Converting each group of 8 bits to an ASCII character

c) Adding a \0 string termination character to the end

 

However, acc_fetch_tfarg_str(), acc_fetch_value() and vpi_get_value()

say nothing about how strings should be returned.

 

Here is the results from a major commercial simulator for the test case

attached.

 

display(), s:        test

display(), t:        .txt

display(), r:        test        .txt

tf_getcstringp(): arg1 = test.txt

tf_getcstringp(): arg1 = test.txt

acc_fetch_tfarg_str(): arg1 =         test        .txt

acc_fetch_tfarg_str(): arg1 =         test        .txt

acc_fetch_value(): arg1 =         test        .txt

acc_fetch_value(): arg1 =         test        .txt

vpi_get_value():         test        .txt

vpi_get_value():         test        .txt

 

In this simulator these functions don't follow the same rules as
tf_getcstringp()

but they are consistent with $display.

 

Regards,
