Grading Update: E-mailed Homework 4 grades. Homework 5 grades will be sent tomorrow. Course grades will be available tomorrow unless it's tough to choose the breakpoints, in which case they will be ready early Tuesday. (That's not a bad thing because the longer I think about grade cutoffs, the higher they get. :-) ) The next grading update will be tomorrow early afternoon.

<blush>Homework 5 was mistakenly copied this morning.</blush> It will be copied again the night of Wednesday, 2 May.
26 April 2001, 13:44:20 CDT
It turns out the bsearch module in Homework 5 is synthesizable, but not in a way appropriate for problems 1 and 2. In those problems, the synthesized module must perform no more than one iteration of the forever loop per cycle. In problem 3 the synthesized module must perform no more than two iterations per clock cycle. The Homework 5 handout has been updated with this information.
25 April 2001, 10:35:56 CDT
Assigned the last homework, Homework 5, due Wednesday, 2 May 2001.
23 April 2001, 19:18:13 CDT
Re-wrote synthesis script that might avoid problems. (Synthesis script would synthesize but would not compile synthesized modules.) The new script is called syn.pl, use it the same way as syn.tcl. Those using Emacs since 19:15 today should exit and restart it to get it to use the new script. Hint: Beware the inferred parallel case. If wildcards are used in case items (e.g., 4'bxxx) the synthesis program might incorrectly infer the parallel case. A workaround is to add extra code in the case item's statement to double check for the correct expression.
20 April 2001, 18:38:22 CDT
Added an improved testbench to the template for Homework 4.. The testbench provides more information and will pass some code that would previously fail.
On some accounts the synthesis script gives an error: error reading output from command: interrupted system call Until a fix is available, use the following workaround: Suppose the error occurs when synthesizing hw04sol.v. Compile the synthesized design, should be in file hw04sol_1.v, as you would any other Verilog file. (In Emacs, by loading it into a buffer and pressing F9.) After that the synthesized design can be simulated.
18 April 2001, 18:30:07 CDT
Added questions on whether it's okay to use the Homework 3 solution in Homework 4 (it is), and about problems with Modelsim and Leonardo to the FAQ page.
18 April 2001, 11:28:18 CDT
The deadline for Homework 4 has been extended to Monday at 23:59 CDT. The files will be copied on Tuesday at 00:30.
The Homework 3 solution will now reject entries such as 90.
16 April 2001, 18:37:45 CDT
Made improvements to the testbench in the template for Homework 4. It should catch more errors and gives more informative "Wrong display" messages.
11 April 2001, 16:03:39 CDT
Linked Set 090, synthesis overview, Set 100, Form 1, Set 110, Form 2, and calculator example in unsynthesizable, and synthesizable, versions to the lectures page. An improved testbench may not be posted until Monday.

Linked a Homework 3 solution to assignments and exams page. This can be used to solve Homework 4. An improved Homework 4 testbench will be posted tomorrow.
10 April 2001, 16:35:12 CDT
There was a problem with the testbench included in the template for Homework 4. The testbench would report everything was okay but would not actually do any tests. The posted code is now correct, if you've already copied it then change the line that looks like:
input [159:0] cmd;to
input [799:0] cmd;To verify that the testbench is working, trace the key_code input to your module (using the wave window).
9 April 2001, 19:56:18 CDT
