Elaborate tran devices
...
The tran devices include tran, rtran, tranif0/1 and rtranif0/1. These
are all elaborated as options on a NetTran device. It is still not
clear the best way to present tran devices via the ivl_target.h API.

Get parameter ranges as far as the netlist form.
...
The pform is now translated/elaborated into NetScope objects. All that
remains is to check the parameter values against the ranges. This is
to be done in the evaluate_parameters() method.

Handle the abs() function in net context.
...
In net context we have to create a node that does the abs() function
for us. Elaborate that node and handle it all the way down to vvp.

Add file and line information for parameters, etc.
...
This patch adds file and line information for parameters and
local parameters. It also adds file/line stubs for signals in
the tgt-* files. It adds the pform code needed to eventually
do genvar checks and passing of genvar file/line information.
It verifies that a genvar does not have the same name as a
parameter/local parameter.

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.

This patch adds code to push the file and line information

runtime. For modules, this includes the definition fields.

This patch fixes some allocation problems (mostly in the parser

where uninitialized variables were used. All found with valgrind.
There are still 100 tests that have problems. Many of these appear
to be related.

Add support for delaying constants at T0.

This patch adds support for delaying constants at time zero. It also
cleans up the code in elab_net.cc to use this capability instead of
building it with an extra BUFZ to carry the delay information.

Add signed bit based power to continuous assignments.
...
This patch adds the power operator for signed bit based values
in a continuous assignment. It also fixes a few other power
expression width problems. The expression width is still not
calculated correctly, since the correct method can produce huge
possible bit widths. The result is currently limited to the width
of the native long. This is because lround() is used to convert
from a double to an integer. A check in the code generator protects
the runtime from this limitation.
2008-02-11 20:06:41 -08:00

Add unsigned bit based power support to normal expressions.
...
This patch adds bit based power support to normal expressions.
It also pushes the constant unsigned bit based calculation to
the runtime until the bit based method can be copied to the
compiler. Continuous assignments also need to use this type
of calculation.

Support delays for all operators in a continuous assignments.
...
Previously only the logical operators (~, &, |, ^, etc.) supported a
delayed value in a continuous assignment. This patch should extend this
to all operators. An extensive check of real values was done. The same
will be done shortly for bit based nets.
Checks for constructs currently unsupported in continuous assignments
provide a more explicit message (** operator, real user functions,
{!, && and ||} operators with a real argument).

Generate explicit locals in the vvp target.
...
With this change, local symbols are not emitted in the vvp target,
but are marked as local. When thus marked, the vvp run time does not
offfer any VPI access and the signals (net or var) are effectively
invisible.

LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

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.
