This is macro defination and when I use this macro, its break the syntax checking

`GET_TIMEOUT_FROM_CMD_LINE(deadlock_timeout, "deadlock_timeout", "deadlock timeout", 'd1000000)
    `GET_TIMEOUT_FROM_CMD_LINE(starvation_read_timeout_base, "starvation_read_timeout_base", "read starvation timeout base", 'd500000)
    `GET_TIMEOUT_FROM_CMD_LINE(starvation_read_timeout_per_beat, "starvation_read_timeout_per_beat", "read starvation timeout per beat", 'd1000000)

:) I really appriciate your work,
thats very nice feature to see macro Expansion view. It will surely be
helpful.

cant wait to get that release. :)

Thanks

Thanks for reporting this! The pre-processor was tripping over the escaped
macro-parameter reference inside the string. This issue will be fixed in
the 1.8.8 release.
Also in the 1.8.8 release is a first version of a Macro Expansion view,
that was very helpful in giving me a first-level indication of where the
issue was.
