VHDL visualiser

[Rick North]

Hi All,

I have found HDL analyst from Synplify to be very help full when
debugging or trying to understand a larger design. It is simple to
filter paths and so forth. I have glanced at ISE which has a similar
viewer but not as well developed as HDL Analyst (my opinion). ModelSim
has a viewer as well but rather bulky.

Does there exist any other vhdl viewer which I have missed?

Regards,

I will try it, one draw back which is rather ugly with HDL Analyst is
that it does not handle records well. It simply states the name of the
record with the number of signals listed from 0 to 240 for example. So
the record elements names are not preserved.

type My_Record_Type is
record
answer : unsigned(7 downto 0);
status : unsigned(2 downto 0);
last_post : unsigned(3 downto 0);
index : unsigned(1 downto 0);
strobe : bit;
end record;

would look like my_record(17 downto 0) stripped from the names inside.
Even more horrible if one has several records with in one record.

Hi Rick,
If you are just looking for a visual schematic, the best tool i have
known so far is debussy from novas. very cool tool. do try it.
