-Minimizing bug-inducing code
-============================
-
-In some cases, the part of the code that causes the bug is clearly visible
-and the design can be easily manually reduced. In other cases, the bug is
-caused by a complex interaction of many parts of the design, and it is not
-clear which parts are necessary to reproduce the bug. In these cases, an
-Open Source tool called `sv-bugpoint
-<https://github.com/antmicro/sv-bugpoint>_` can be used to automatically
-reduce a SystemVerilog design to the smallest possible reproducer.
-It can be used to automatically reduce a design with hundreds of thousands of
-lines to a minimal test case while preserving the bug-inducing behavior.
-
-Please refer to the `README
-<https://github.com/antmicro/sv-bugpoint/blob/main/README.md>`_ file for more
-information on how to use `sv-bugpoint`.

-   Indicates certain constructs where non-blocking assignments to unpacked

-   initialization/reset code:
+   .. TODO better example
+
+   This indicates that the initialization of an array needs to use
+   non-delayed assignments.  This is done in the interest of speed; if
+   delayed assignments were used, the simulator would have to copy large
+   arrays every cycle.  (In smaller loops, loop unrolling allows the
+   delayed assignment to work, though it's a bit slower than a non-delayed
+   assignment.)  Here's an example

   .. code-block:: sv

         always @(posedge clk)

                for (i=0; i<`ARRAY_SIZE; i++)

+                    array[i] = 0;  // Non-delayed for verilator

-   While this is supported in typical synthesizeable code (including the

-
-   1. If the above loop is inside a suspendable process or fork statement.
-
-   2. If the variable is also the target of a '<=' non-blocking assignment

-   3. If the element type of the array is a compound type.

-Because general constrained randomization is a co-NP-hard problem, not all
-cases are implemented in Verilator, and an external specialized SMT solver is
-used for any non-obvious ones.
-
-The ``randomize()`` method spawns an SMT solver in a sub-process. Then the
-solver gets a setup query, then the definition of variables, then all the
-constraints (SMT assertions) about the variables. Since the solver has no
-information about the class' PRNG state, if the problem is satisfiable,
-the solution space is further constrained by adding extra random constraints,
-and querying the values satisfying the problem statement.
-The constraint is currently constructed as fixing a simple xor of randomly
-chosen bits of the variables being randomized.

-The runtime classes used for handling the randomization are  defined in
-``verilated_random.h`` and ``verilated_random.cpp``.
