BUG LIST FOR CLA v2
===================
additions to craig.graham@newcastle.ac.uk
[18/7/93]
o The Logic Analyser Window has an intermitent display bug when updating
as a background window in interactive simulation mode.
I know what the problem is, but haven't got time to fix it yet.
o There is a bug in the delete component routine but it doesn't show up
often (but when it does it sh*ts on your design real bad). Haven't
managed to characterise it yet - anyone who can please get in touch.
*** [21/3/94] I think I've got this one licked now - it was a problem
*** with the merge routines not re-mapping link ID's from inside
*** blocks......
[20/7/93]
o The majority of the logic levels available from the Word Generator do
nothing (HLZX) - sorry, they're there in readiness for the next release
(I'm working on a more complex simulator at the moment that supports
these but is to buggy to release right now).
[1/9/93]
o At present the screen is double buffered - this means that if you are
going to run CLA in a high graphics mode then you need a LOT of
memory. To get an idea of the scale of this problem, 800*600*8bit mode
on my 4 Meg Falcon (with NVDI loaded but GDOS turned off) will only
allow circuits up to 9400 gates to be drawn....this ceases to be a
problem in lower graphics modes (800*600*1bit, etc).
The double buffering could be made switchable if anyone wants me to,
this makes scrolling interactive mode simulation a lot slower but will
be easy enough to implement.
[14/11/93]
o CLA doesn't work in Falcon True colour mode - I'm not sure why.....it's a
problem with the way the blit buffer is calculated I think...vqt_extend
only returns a valid number of colours up to 32000(ish) & True colour mode
has more......solutions on a postcard please.
[25/11/93]
o There is a bug which can result in the system hanging - don't know why yet.
*** [November 94] : I think I've got this one now - it was calling
*** form_alert with the mouse button down, which hangs some TOS versions.
[3/2/94]
o NVDI off-screen bitmaps conflict with SpeedoGDOS. So I've put a detect in
which will disable OSBM's when Speedo is loaded - at least until I've got
my head round using MEMORY.SYS for OSBM support under Speedo.
o Text Labels for rotated objects are not handled correctly by the GDOS
output system - they aren't rotated to match the on-screen display.
** Only if you are using CLA vector fonts instead of GDOS ones.
[15/4/94]
o Bulbs don't print out from GDOS.
o CLA crashes when you open a file selector on a TT in 24bit colour under Mag!X.
I think this is connected to the screen buffering (a similar error to using
falcon 16-bit per pixel mode). Solution - don't use 24bit colour mode (you
don't need it in CLA anyway).
