Jim Lewis replied to the topic Cannot compile the library with Modelsim 10.5b in the forum OSVVM 7 years, 5 months ago
I test with QuestaSim 10.5b so if you have the compile order correct, you should be fine.How did you compile it? Did you use the osvvm.do file? See: https://github.com/OSVVM/OSVVM/blob/master/osvvm.doDid you use the directions in the OSVVM_release_notes.pdf? See: https://github.com/OSVVM/OSVVM/blob/master/doc/osvvm_release_notes.pdfI note…[Read more]

Jim Lewis replied to the topic Limitation using MemoryPkg in the forum OSVVM 7 years, 6 months ago
Hi Eilert,In the 2008 standard it says:An implementation shall choose a representation for all floating-point types except for universal_real that conforms either to IEEE Std 754-1985 or to IEEE Std 854-1987; in either case, a minimum representation size of 64 bits is required for this chosen representation.I think this changed before 2008,…[Read more]

Jim Lewis replied to the topic Reporting ignored bins in the forum OSVVM 7 years, 8 months ago
Hi Roger,I just did a code review regarding AtLeast. Looking at the code, the AtLeast value is the maximum of the one specified by AddBins (the way I usually show to enter it) and the value specified by GenBin (also specified by a first integer value – but then also requires at least 4 parameters be used). Hence, if you specify both, you may be…[Read more]

Jim Lewis replied to the topic Scoreboard Package Error in Questa in the forum OSVVM 7 years, 11 months ago
That unfortunately is a known bug. 10.4 brought some new cool features, but some how broke for the scoreboard in a way that I could not figure out how to work around. If you are just working with the primary releases, the following versions also exhibit the issue: 10.4, 10.4a, 10.4b, 10.4c. 10.3 was fine. 10.4d and 10.5 are fine. The…[Read more]

Jim Lewis started the topic RandCovPoint(0.0) and potential changes in the forum OSVVM 12 years, 10 months ago
Hi,This post is to discuss a planned change to RandCovPoint. Its current declaration is:impure function RandCovPoint ( PercentCov : real := 100.0 ) return integer_vector ;Currently PercentCov is used to enable two separate concepts. If PercentCov is greater the current minimum coverage, then PercentCov represents a coverage goal. Anything…[Read more]
