Account for swithes linked to nexus in ivl_target.h API.
...
Switches can connect to a nexus too, so add the missing nexus support
for that in the ivl_target.h API.
2008-06-01 14:29:27 -07:00
ca756f3ec3
Bring switch information out to the ivl_target API.
...
This involves defining the API for switches and cleaning up the
elaborated form to match the defined ivl_target API. Also add t-dll
code to support the ivl_switch_t functions, and add stub code that
checks the results.

Elaborate abs() is continuous assign expressions.
...
In continuous assign expressions, the abs() operator can't easily be
burried in generic unary handling, so add the IVL_LPM_ABS type and
generate it as needed.

Add ifnone functionality.
...
This patch adds ifnone functionality. It does not produce an
error when both an ifnone and an unconditional simple module
path are given. For this case the ifnone delays are ignored.

Fix lexical scopes within case-generate alternatives.
...
Case-generate alternatives create sub-scopes that need to be scanned
by the scope scanner in order to get function definitions etc. that
are defined lexically within generated scopes.

Support delay of user function output
...
When used in continuous assignments, user defined functions may have
delayed output. Handle that by generating the proper .delay node when
needed to delay the output of a .ufunc node.

Give delay paths scope.
...
Delay paths need a scope. This helps the code generators bind the
modpaths to the correct scope. This patch doesn't actually make use
of the information, it just makes it available to code generators.

Pass local scope precision from compiler to vvp/etc.
...
This patch adds ivl_scope_time_precision() to the compiler which can
be used to extract the local scope precision. tgt-stub and tgt-vvp
have been modified to use this new function and output a value that
is appropriate. The vvp runtime has been altered to use this new
data which is accessed with the vpip_time_precision_from_handle()
function. vpiTimePrecision uses this function to return the correct
precision.
