Preprocess and write out files that do not have any macros that need
expanding. By default, files that do not need processing are not written
This option may speed up simulator compile times; the file will always be found in the preprocessed directory, saving the compiler from having to search a large number of -v directories to find it.
|--axiom||Special Axiom ATHDL enables/disables added around unreachable code.|
|--call-error <function>||When $uerror (or $uassert etc.) wants to display a message, call the specified function instead of $display and $stop.|
|--call-info <function>||When $uinfo wants to display a message, call the specified function instead of $display.|
|--call-warn <function>||When $uwarn (or $uwarn_clk etc.) wants to display a message, call the specified function instead of $display and $stop.|
|--date||Check file dates and sizes versus the last run of vpassert and dont process if the given source file has not changed.|
|--exclude||Exclude processing any files which begin with the specified prefix.|
|--help||Displays this message and program version and exits.|
|--language <1364-1995|1364-2001|1364-2005|1800-2005|1800-2009|1800-2012>||Set the language standard for the files. This determines which tokens are signals versus keywords, such as the ever-common do (data-out signal, versus a do-while loop keyword).|
|--minimum||Include __message_minimum in the $uinfo test, so that by defining __message_minimum=1 some uinfos may be optimized away at compile time.|
|--noline||Do not emit line directives. If not specified they will be used under --language 1364-2001 and later.|
|--nopli||Delete all simple PLI calls. PLI function calls inside parenthesis will not be changed, and thus may still need to be manually ifdefed out. Useful for reducing the amount of ifdefs required to feed non-PLI competent synthesis programs.|
|--nostop||By default, $error and $warn insert a $stop statement. With --nostop, this is replaced by incrementing a variable, which may then be used to conditionally halt simulation.|
|--o file||Use the given filename for output instead of the input name .vpassert. If the name ends in a / it is used as a output directory with the default name.|
|--quiet||Suppress messages about what files are being preprocessed.|
|--realintent||Special RealIntent enable/disables added around unreachable code.|
When ifdef SYNTHESIS is seen, disable coverage. Resume on the else or
endif. This does NOT follow child defines, for example:
|--timeformat-units units||If specified, include Verilog $timeformat calls before all messages. Use the provided argument as the units. Units is in powers of 10, so -9 indicates to use nanoseconds.|
|--timeformat-precision prec||When using --timeformat-units, use this as the precision value, the number of digits after the decimal point. Defaults to zero.|
|--vericov||Special Vericov enable/disables added around unreachable code.|
|--verilator||Special Verilator translations enabled.|
|--version||Displays program version and exits.|
|--vcs||Special Synopsys VCS enables/disables added around unreachable code.|
These Verilog pseudo-pli calls are expanded:
/*vp_coverage_off*/ Disable coverage for all tools starting at this point. Does not need to be on a unique line. /*vp_coverage_on*/ Re-enable coverage after a vp_coverage_off. Does not need to be on a unique line. $uassert (case, message, [vars...] ) Report a $uerror if the given case is FALSE. (Like assert() in C.) $uassert_amone (sig, [sig...], message, [vars...] ) Report a $uerror if more than one signal is asserted, or any are X. (None asserted is ok.) The error message will include a binary display of the signal values. $uassert_info (case, message, [vars...] ) Report a $uinfo if the given case is FALSE. (Like assert() in C.) $uassert_onehot (sig, [sig...], message, [vars...] ) Report a $uerror if other than one signal is asserted, or any are X. The error message will include a binary display of the signal values. $uassert_req_ack (req_sig, ack_sig, [data_sig,...] ) Check for a single cycle request pulse, followed by a single cycle acknowledgment pulse. Do not allow any of the data signals to change between the request and acknowledgement. $ucheck_ilevel (level ) Return true if the __message level is greater or equal to the given level, and that global messages are turned on. $ucover_clk (clock, label) Similar to $uerror_clk, add a SystemVerilog assertion at the next specified clocks edge, with the label specified. This allows cover properties to be specified inline with normal RTL code. $ucover_foreach_clk (clock, label, msb:lsb, (... $ui ...)) Similar to $ucover_clk, however cover a range where $ui in the expression is replaced with the range index.
Range is "msb:lsb" to indicate from msb downto lsb inclusive, and/or a comma separated list of values.
for ($ui=msb; $ui>=lsb; $ui=$ui-1) begin if (expression with $ui) $ucover_clk(clock, label ## "_" ## bit) end
However theres no way to form a label from a for loop (as psudocoded with ## above), thus this macro.
$ui Loop index used inside $ucover_foreach_clk. $uinfo (level, message, [vars...] ) Report a informational message in standard form. End test if warning limit exceeded. $uerror (message, [vars...] ) Report a error message in standard form. End test if error limit exceeded. $uerror_clk (clock, message, [vars...] ) Report a error message in standard form at the next clock edge. If you place a $uerror etc in a combo logic block (always @*), event based simulators may misfire the assertion due to glitches. $uerror_clk fixes this by instead creating a temporary signal and then moving the assert itself to a new clocked block at the specified edge. Note any variables printed will be the values at the time of the next clock edge, which may differ from the value where the $uerror_clk is assigned. $uwarn (message, [vars...] ) Report a warning message in standard form. $uwarn_clk (clock message, [vars...] ) Report a warning message in standard form at the next clock edge. See $uerror_clk.
