Does anybody know an ftp adress or some more about this? adress? ************************ article from comp.lsi **************** After several inquiries, I realized that I'd better post this on the net rather than try individual replies: Here is the README file from the University of Pittsburgh simulator. It has the names of the developers, I guess they can be contacted regarding how to obtain a copy of the software. >From what I could find out - Syracuse Universiry paid about $75 for the simulator - probably a s/h + cost of tape charge. Shantanu Ganguly Syracuse University sganguly@cat.syr.edu -----------------README FILE-------------------------------------- Last Modified: 2/6/90 -- Alan R. Martello, University of Pittsburgh OVERVIEW -------- This is the README file for the VHDL toolset distributed by the University of Pittsburgh. The tools currently supported are a VHDL 1076 Compiler and a Simulator. The compiler parses (hopefully) the entire 1076 syntax. A database is built from a subset of the VHDL parsed (the VHDL which is parsed but not built into the database is thrown out after warnings are generated). The subset of VHDL parsed is discussed in the man pages. An event driven simulator exists which can read the database generated and allow for simulation of the output network. The tools simulate both concurrent and sequential VHDL. The concurrent VHDL is simply built into a network of gates and the sequential VHDL is translated to 'C' code. To perform a simulation utilizing sequential code, a new simulator must be linked to include the translated constructs. PLATFORM -------- The only platform totally supported is the SUN-3 series (since these are the computers used for the code development). However, we attempt to allow the tools to be run on a variety of platforms. All the tools are textual and may be run on "dumb" terminals. The tools have been known to work on the following platforms: - Sun-3 - Sun-4 - VAX/VMS - VAX Ultrix - Apollo PORTING ------- The code has been written in fairly generic 'C' and should be easily portable to any "standard" (Berkley/4.2) Unix environment. A System V port should not be much of a problem, the only troublesome area should be "strings.h". All I/O is done via "standard" Unix calls and any Unix compatible library should suffice. There has been substantial interest in a PC port of the tools. However, this is not currently being attempted by us. The standard Unix YACC could not be used to generate the VHDL parser due to the number of production rules associated with the grammar. Instead, we use the GNU tool Bison to compile the grammar and create the parser tables. We find this tool more robust, reliable, and faster than YACC. The tools assume that they are running in a "virutal" environment since the parser generated by Bison is extremely large and each data structure in the threaded database graph generated is allocated dynamically. If you have successfully ported the tools to another environment, we are interested in receiving a description of the environment (along with any code modifications). Bug fixes and enhancements are made as time permits and this allows for continued support of multiple platforms. DISCLAIMER ---------- This code has evolved over the past few years from a Master's thesis to a PhD project. In the process, it has undergone at least one substantial rewrite and variaous areas have been greatly reworked. The work in its current form has NOT been supported directly either by the University of Pittsburgh or by any outside funding. As such, enhancements and bug fixes are only performed to further our current research goals. NOTE: these tools are Copyright 1989-1990 University of Pittsburgh and Alan R. Martello and as such, may NOT be sold either in whole or part without the written consent or the authors.

The two main tools are vcomp, a VHDL 1076B parser-compiler, and vsim an interactive simulator. Vcomp parses the complete language but only generates output for a small, but useful, subset of the language. Process statements are compiled into C source code for run time linking with the simulator vsim. We are including source code in this distribution, including all the parsing tables etc. We have used bison, the GNU version of yacc for our parser. We also are distributing a small set of examples and some "courseware" which we use when we lecture to our students about VHDL in our digital design and VLSI courses. The software is all "Copyright University of Pittsburgh" and we are issuing a non-exclusive, non-transferable license, the software is not "public domain". Our purpose is to let more people have access to the VHDL language for experimentation and research, not to support commercial products. We are distributing the software on Sun cartridge tapes for a fee of $150. Tapes will be written in "Unix tar" format. Unfortunately, we do not have the staff to answer phone questions. We will try to respond to computer and U.S. mail requests. If you want a copy of the tools, please read and sign the accompanying license agreement and letter of assurance, and send a check made out to "Department of Electrical Engineering, University of Pittsburgh" for $150 to: Prof. Steven Levitan Department of Electrical Engineering 348 Benedum Engineering Hall University of Pittsburgh, 15261 Internet: vhdl@ee.pitt.edu Just to let you know, we are currently working with our colleagues at Penn State University to broaden the set of tools we will distribute to include the rest of the Keystone synthesis tools, these allow our students to go from VHDL into CMOS VLSI layouts, I will let you know when that extended package is available and how to get that in the near future. ------------------------------ Date: Fri, 08 Feb 91 09:14:27 BRA From: Luiz Felipe Perrone <COS99284%UFRJ@nervm.nerdc.ufl.edu> Subject: Space-Time and Conditional Event Simulators To: simulation@bikini.cis.ufl.edu I'm a graduate student in the Federal University of Rio de Janeiro and I'm doing research work for my thesis in Time Warp. This was the first research work on distributed simulation in our department and as other students became highly motivated by this subject we are beginning to gather literature for two other simulator projects: one using the Space-Time paradigm and the other the Conditional Event Approach. As we happen to know only one paper about each of these and we need a lot more of information on experiments with these new methods, we would like to know if anybody can point out something else to us.These articles we have are the seminal papers on the paradigms by Profs. Chandy and Sherman.

McInnis and Cheng-Kang Frank Liu (1986) "Kinematics and Dynamics in Robotics: A Tutorial Based Upon Classical Concepts of Vectorial Mechanics",IEEE Journal of Robotics and Automation. Vol:RA-2, No:4, December 1986. If you don't have this article please ignore this posting. The authors differentiate equation (2) on page 181 to get equation (3). (2): Vp = Vi + P(o)i/i + Wi X Pi to get (3): Ap = Ai + P(oo)i/i + 2Wi X P(o)i + W(dot)i X Pi + Wi X ( Wi X Pi) ^ | | I only get one of these. ie. a one instead of a two. Please, someone, explain. How is this done, or is this a typo ? If it is a typo, what is the correct answer. PS: I hope this makes sense. Apologies for the way that I have done sub/super scripts. Much thanks in advance.
